anyone else seeing very long AS paths?

Anyone have an estimate as to when these long announcements began? Seems 
like the first reports appeared just before noon, UTC-05.

We noticed a significant dip in Internet traffic to AS11579 for a few 
minutes last night (19:00 UTC-05) which we've been trying to hunt down the 
cause of. At first glance, the two events seem unrelated. Anyone else see 
anything similar?
