knightly returns 503 service unavailable on /account redirect

I've seen this happen a couple of times. Noticed this morning so reporting.

It looks like something might be failing with the account check in knightly's OOD login sequence. I go to main url and then get redirected through the dashboard to the /account url which then reports a failure.

The core issue is that I shouldn't be redirected because I have an account. But the end problem is that the /account app isn't functioning right and returns an error instead of an account status page.
