Unofficially, I think no.  I would be concerned in one relay, as fast as 
blutmagie's are, could have this much impact on the network.

My sneaking suspicion is that it's related to China unblocking the Tor network 
in April, and re-blocking it on May 4th.  Cutting a few hundred thousand users 
out of the network hopefully has a larger affect on performance than 1-4 fast 
relays.

Many chinese users will simply switch to bridges, but the total number of 
bridge users in china is less than the total number of tor users when Tor is 
unblocked.
