I tried running some queries just now, but get this error:

Login failed. The login is from an untrusted domain and cannot be used with Windows authentication.

tried both http and https, but same error. Not trying to log-in to anything even, just run a query.

Also I get runtime error after clicking on "Compose Query".

    I tried to repro, but I'm not even getting that. I'm getting a 500 Internal Server Error, with standard the "how to turn custom errors on" instructions. Feb 19, 2015 at 6:50

    I'm hitting this too. On some queries only... for example I can't run this, but I can run this. Feb 19, 2015 at 10:50

  • Can you give it a try now? It was stuck in an especially bad state after an internal issue we had exhausting UDP ports which hosed DNS and caused a great disruption in the force. Feb 19, 2015 at 12:01
  • Yep, works here as well

Apologies this was still erroring out - the SQL auth used here was stuck in a very bad state after an internal DNS failure earlier.

We've kicked it with (likely excessive) force but it did resolve the issue.
