Frequent failures because SQL Server is not able to start

In the last couple of weeks, we've been getting build fails because SQL Server, which we need to run tests, cannot start on the build worker.

Here's the error message:

Starting SQL Server 2016 Developer
Start-Service : Service 'SQL Server (SQL2016) (MSSQL$SQL2016)' cannot be started due to the following error: Cannot start service MSSQL$SQL2016 on computer '.'.
At line:1 char:1
+ Start-Service 'MSSQL$SQL2016'
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : OpenError: (System.ServiceProcess.ServiceController:ServiceController) [Start-Service], ServiceCommandException
    + FullyQualifiedErrorId : CouldNotStartService,Microsoft.PowerShell.Commands.StartServiceCommand

Building the same commit again may pass or sometimes fail again with the same issue.
This is causing our build to take much longer than usual only to fail and tip off developers to think they may have issues in their code and this is disrupting our process.

    This is likely a performance issue due to some upgrades happening on our servers. We try to keep it as transparent as possible thought there are some occasional manifestations.

    If this persists past the weekend please let us know.

    @mothman: things should be good now. If you see any slowness or errors, please let us know.

    Thank you Owen and Ilya, it is much better this week.
    However, I just ran into the same issue in one build:

    Are you starting SQL server from custom script or as described here?

    I'm using the services section in appveyor.yml:

      - mssql2016

    Checked that build and I believe that it is still a residual effects of I/O issues we had recently and fixed 2 days ago. I think it should not re-occur.

    I see. Though we solved capacity issues, some nodes in our datacenter seems to have I/O issues. I believe this build happened to run on one of those nodes. We are in the process of replacing them. I cannot give specific date, but I should be completed in 2-3 weeks.Meanwhile you can replace services.mssql2016 with - appveyor-retry net start MSSQL$SQL2016 at say install stage. This will be more reliable for now.
