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?

Is there a reason you don't use something like "bgp maxas-limit NN" on

your transit sessions?

We saw this too, but it stopped at our transit routers.  There was
actually another a few days ago.
