Public bug reported:
It looks like requests to the remote server time out more often than we
care to admit. When that happens, we treat the failure as a temporary
and surprising error and disable remote server access for two hours.
We need something more sophisticated so we can react to timeout errors
with a different strategy than to other temporary surprising errors. The
problem is that a dead server is indistinguishable from a slow one, so
we probably need some exponential back-off strategy, or count the number
of consecutive timeout failures and trigger the full two-hour back-off
only if some threshold is exceeded.
