They're back now. Problem posted elsewhere. However what annoys me

It's called exponential back-off. The idea is that it avoids giving
the server a Denial-Of-Service attack as more and more clients time
out and try to 'phone home'.

I take your point, but they could put some upper limit on it. Many PCs 
running BOINC are unattended - e.g. servers - and don't have a user logged 
in to "give it a kick".
