    Big routing leak from a Verizon downstream (AS396351) caused major disruptions across the #Internet this morning. Over 20,000 prefixes from ~2,400 ASNS impacted. Thread from @atoonk / @bgpmon provides more insights:

    wow waking up to some BGP madness! Looks like many (all) of @Cloudflare AS 13335 prefixes are being rerouted through AS396531 (Allegheny Technologies) and Verizon AS701 is providing that transit via that path! Ugh not good! will dig more ... #BGPleak
