It's been a while, but I do believe it was temporary for us. Like the 
EC2 instances output would drop from say 10MB/s capacity down to 150kb/s 
for blips of anywhere between 2 and 10 minutes. The degradation in 
performance all but stalled everything we had that kept expecting 
multiple MB/s of output to be possible.
