We found out last night that there was a "legacy" route on zayo's side that was incorrectly routing our traffic. It seems ok now. Sent from ProtonMail Mobile -------- Original Message -------- On Apr 9, 2020, 14:23, Forrest Christian (List Account) wrote:

Replying on list...as others may be seeing something similar.

We had a problem which started over the weekend involving Allstream. One of their customers were announcing our prefixes, resulting in broken connectivity.

I ended up calling the Zayo NOC, since Allstream seems to be part of zayo. I also figured their NOC could earn some of the money we're paying them for transit. If you're not a zayo customer, YMMV.

The report we got back was that some customer of Allstream was announcing our prefixes "illegaly" and filters had been applied. They also implied a bit of clue would be dispensed. Not sure if this is your issue or not.
