I can confirm that as well, don't think its related with python 2.7 or HRD. I am seeing high latencies similar to yours with python 2.5 and MS just right now, even GAE console takes ages to load and some times throws errors. I noticed that similar slowness happens few times per week, I wonder will it ever become stable?
