Yes, it's horrid. I've been peering with PSI for going on three years, and it's never been as bad as it is now.
I took advantage of their "free peering" offer back in the day, and ended up peering with them for about 18 months (06/1999 - 01/2001). It took about 9 months for them to get the circuit installed. For the first few months, everything was great, but then we started getting massive spikes in latency (300-700ms) just getting across the pipe between my router and PSI's router. I liken it to owning an old Audi - they were great when they ran, but spent more time in the shop than on the road. The process of opening tickets and getting clued people in their NOC to talk to me was an adventure. PSI, much like some other providers, went to great pains to try keeping $CUSTOMER from having a direct path to $CLUEDPEOPLE. They could never adequately explain the latency, other than it would mysteriously go away and re-appear, more or less independent of the amount of traffic on the circuit. Eventually an upper-level engineer told me that the saturation was due to congestion on their end of the pipe, and getting some fatter pipe in there would take 60 days. Fine. 90 days later, the bigger pipe is installed on their end and the latency goes away for a few weeks, then comes back. Wash. Rinse. Repeat. A few more months of that, and I cancelled the peering.
oddly enough, we see 30+ msec across a DS3 to them, which isn't that loaded (35 to 40 mb/s).
Then, behind whatever we peer with, we see over 400 msec, with 50% loss, during business hours.
