Go2.me was crashing today. It seems to be more stable now, but unfortunately, I haven't been able to determine the cause. A review of the server logs on Google App Engine show that the error is deep inside Google's code, not mine.
I updated Go2.me today, with what I think is an unrelated bug fix (and a new feature). It seems to be up for now, so I'm not sure if I resolved the problem or not.
In case any developers who read this blog might have seen a similar problem, here are a couple of backtraces from my error logs that seems to be related to the problem:
