Clicking on "Continue" or "Start" in the problem list results in a white screen (the server returns empty content).
This came at a really bad time...

Same here :(((
And I am on the mood of writing problems...
Is there any update on when this problem will be fixed?
Fixed. Sorry about it.
It seems that this issue might be still there for problems that were created during this down period. I have one of these:
Attempts to "Start" this problem give empty response, making it unusable. This is not a problem, I can just ignore it, but still worth mentioning.
It happened again.
I have now seen two times when this started occurring. In both cases, I generated a contest PDF and it started to load for an unusually long time. Eventually I just ended up on a CloudFlare timeout page. And after that, clicking the "PDF from working copies" link (or all of the "Continue" links) return white screens.
This is not to say that this bug is caused by creating a contest PDF that takes too long, maybe a PDF will take too long as a consequence of whatever causes this bug.
