SmartLink service needs to be more robust

I can see that there are a quite a number of posts and with that occasions when the SmartLink Service has been down for remote action.

If a service like SmartLink is needed for users to run remote then one would expect to have a design with uptime guarantee 99.99% isch.

So for the moment I would say we are having a bad design and I can see this as a showstopper for to promote FLEX remote usage, at least based on SmartLink-platform.

A more selfcontained solution based on VPN is probably the better option until SmartLink gets more reliable.

What is your view and/or the official statement from Flex ? 

Thank you in advance / Tilman SM0JZT

    I do not agree. There have been very few outages with Smartlink. I venture to suggest that we have more with our service provider.

    I haven't experienced any down time with SmartLink. I do a lot of remote access with SmartLink and found it very reliable. The few times I have experienced issues I found it to be not SmartLink problems but with my local service or the 3rd party service I was trying to use.  
    I don't know the details of your failures but I would question other network issues instead of SmartLink.

    I blame the Uzure service which I think is by Microsoft. Surely we should expect better reliability than this from Microsoft?

    With an ever increasing number of users of SmartLink, Flex should publish a document which clearly states their uptime objectives and how they will deal with growth. As a small company, they are completely dependent on 3rd party suppliers. I would suggest Flex provide full support for VPN protocols like OpenVPN which is very popular and has phone/tablet apps as well. Currently Flex radios are not compatible with OpenVPN, so users VPN users must resort to SoftEther which is much less user friendly than OpenVPN. Old protocols like PPTP are not supported by Apple any more, for example.

    I do not agree with your statement that SmartLink is not enough robust. I have been using it extensively since it's release over a year ago. Including 48 hour contests and I have never experienced a down time. Never. And I am quite demanding with respect to my contest needs.

    As I provide quite a bit of support for Flex users I must say that many times "down time" issues of SmartLink are related to router, PC, broadband network access or other non Flex hardware problems. Sometimes issues are regarding registration issues of SmartLink it self. But this has nothing to do with robustness.

    Of course, VPN is an alternative but the I do not see it as a simple user friendly alternative. I have used Softether myself and it works fine. But to be able to easily work from several platforms; PC, smartphone, iOS makes SmartLink the obvious choice for me even though I consider myself quite technically oriented in this respect.

    Right. This is what I think we schould be asking for. A statement on what could be expected from the service. It is fine that it seems to work most of the time. But what is needed is a official statement on quality and process. Again . I would also like to have a OpenVPN alternative, where one would have a selfcontained solution.

    What is currently the status? Are connections already possible with Smartlink?

    I am waiting to register my newly purchased 6400 for remote used with the Maestro. Since yesterday evening 23:00 LT I was not possible to reach the server, even not login with my Smartlink account

    Still not up as of this time.  11:00 UTC   9/5/18   Flex is aware of the problem and hopefully it will be resolved very soon.

    Our Smart Link Service relies on Microsoft Azure to manage the authentication process.    Like you, we are a customer waiting for our services to be made available.

    This is the update from Microsoft as of 15 minutes ago.  And, from my tests,  it looks like things are starting to come up, but it might be a few more hours for them to be at 100%.  Lots of boxes to restart here.

    I just tested my iPhone on SmartSDR and it came right up.

    PRELIMINARY ROOT CAUSE: A severe weather event, including lightning strikes, occurred near one of the South Central US datacenters. This resulted in a power voltage increase that impacted cooling systems. Automated datacenter procedures to ensure data and hardware integrity went into effect and critical hardware entered a structured power down process.
     
    ENGINEERING STATUS: Engineers have restored access to storage resources for the majority of services, and customers should be seeing signs of recovery.  Engineers are continuing to work on any residual storage impact to fully mitigate this issue. The current mitigation workflow is outlined below:
     
    1) Restore power to the South Central US datacenter (COMPLETED)
    2) Recover software load balancers for Azure Storage scale units in South Central US (COMPLETED)
    3) Recover impacted Azure Storage scale units in South Central US. (Mostly complete)
    4) Recover the remaining Storage-dependent services in South Central US (Mostly complete)

    Azure has availability zones all over the world across all human inhabited continents. By having SmartLink run in more than one availability zone it can be 100% bulletproof. So the real issue here is if SL is designed to be highly available.

    I work in IT and several of the cloud services that we use were down yesterday.  It wasn't just smartlink.  Many Microsoft 365 services were down yesterday.  Sometimes stuff happens....

    Ever played with the Icom 7610? Although it doesn't compare to the Flex, it has a stand-alone server. It never fails unless the radio or the LAN/WAN fails. Perhaps it is possible to change the design philosophy with the same strategy as Icom? I never use Smartlink as the Asus OpenVPN is far superior. It is a kick in the head to use FT8 remotely.

    Flex is just one user of that particular data center and just a very small percentile of users in the overall picture. If a company like Microsoft is vulnerable with all their billion dollar resources, it is very unrealistic for ham radio users to demand more than what Flex is using. This is a hobby.
    I'm sure appreciative that they decided to farm out SmartLink servers with a large data center as compared to maintaining their own server in a bathroom closet.

    Thanks for the update Michael. As a power engineer in a datacentre, I'm fully aware of the nightmare Microsoft must be having over this outage. It's nowhere near as simple as flicking a switch back on, or simply rebooting a few servers or the odd router. They have to be brought back up "gracefully" and likely in a particular order. And that is if the software hasn't been corrupted and has to be reloaded from backup, the PSU's haven't blown and need to be replaced, blah blah....... Let's cut Flex some slack here. It's a Microsoft issue that's affecting a lot of customers. It's also likely that there'll be some business giants hosted there (far far bigger than Flex) and they'll be first in line to get their pound of flesh........

    SmartLink is at the cornerstone of the argument “Why Flex”. As such, it would make sense to design SL with far better resiliency. A single lost 6400 sale pays several times the monthly fee associated with running workloads in multiple availability zones.

    Building in Azure is not the same as running a server in Microsoft’s data center. You can do that, but you are not benefiting at all from the full Azure capabilities.

    I am currently working with a client that runs an app that is existential to the lives of millions of people. If the system fails people would die. The system runs in each US region as well as in Brazil and the UK. The incremental cost of running across the globe is roughly $5,000/month.

    In the test environment, we run a script that randomly fails any number of components and we observe the impact. Happy to say that for the past 6 months the system has been up and running no matter what, including in the past 24 hours.

    Here’s the current state of Azure that shows that you can get away with just to regions if you want to have a resilient app:

    https://azure.microsoft.com/en-us/sta... The point is that there are viable options. What FRS decides to do is their own business decision, making a tradeoff between protecting the grown jewels (SL) vs. the incremental cost.

    Surely this was on the drawing board during the brainstorming sessions but there were no doubt too many cons vs pros. To revert back to what legacy radios are doing would be taking the flexibility out of Flexradio. The pros of a server outweight the cons. What your suggesting would require much more radio resources at the expense of performance and future features. For example, how to manage what radio is authorized to run what level of software. Another example is multi-client. Just isn't going to happen without external authentication.
    Going out via the internet to a 3rd-party multi-level server for authentication was the was to go forward. Downfall, if a zombie apocalypse should happen and the internet is down, remote authentication would eventually be non-existent. I suspect one would have other priorities during an apocalypse besides dxing and contesting remotely.

    Well all I can say about this is we're a hobby.  I would never expect 99.99.  Oh well if it's broke they'll fix it.  In the meantime call your buddies on the local simplex frequency if you need a ham fix.

    I totally agree-----this is a hobby guys! Cheyenne MT. (Norad bunker) does not require 100%! We are acting like it's a life or death situation here with our little hobby radios.

    The idea is very simple. The Flex service will be as reliable as the Microsoft Service. I take it that you all have expressed your dissatisfaction with Microsoft?

    Is Flex responsible if the remote site has a power outage?

    The option for using a individual VPN connection, utilizing VPN software at the shack router, or Softether.net running on the shack computer, has been possible long before SmartLink was introduced.  Many of us have successfully run SSDR remotely on laptops, desktops, or iPads/iPhones before Smartlink was released. 

    it still remains a fallback option when Smartlink disruptions occur.  I still leave mine active for cases just like this.

    Smartlink's advantage is that is provides 1) easy networking solutions for the vast majority of hams who may not be proficient enough with networking to implement their own VPN, and 2) to provide an easy, secure authentication system to protect users from potential hacking. 3) it eliminates the requirement for VPN software to be running on a shack computer or router, and it requires no additional VPN software to be running on the Maestro, remote computer, or IOS device.

    If users desire a direct connection that doesn't involve the authentication system SL provides, they are welcome to establish their own VPN connection with all the required port forwarding, etc.  It isn't that difficult, just a bit tedious to do the first time.

    That is a Microsoft issue also, and people would then demand that Flex cure their horrible latency issue. The entire concept of radio by internet is going to expose the radio users to the internet and it's issues. DDOS and local issues like the number of users simply will affect the service as we add layers of complexity to our hamming.

    And if you are willing to put up with a lesser radio, get a 7610. I shook our new one down last week, and it is meh. Reinforced my decision to go with Flex. And FWIW, I have two Icoms in the shack.

    Amen, Bill.  I am a little surprised that so many people have the internet stacked on top of their radio game, and expect no problems ever. That is simply not realistic. 

    Things like losing the cloud service, DDOS attacks, Internet outages and slowdowns are 100 percent certain to happen. I have a fast connection. But at certain times it isn't for one reason or another. I've lost it a few times and had to reset and reboot the router. All things that would take the Flex remote or Icom's remote service down. 

    We're smart people. If we incorporate an outside service like the Internet into our radio use, we should learn the limitations of the internet just like we should know how to operate our radios.
