  At 06:05 UTC on Jul-27, DDoS mitigation service Voxility (AS3223) leaked over 30k BGP prefixes to its transit provider Lumen (AS3356) for up to 40 minutes causing traffic to affected prefixes to be disrupted or misdirected.

  ICYMI: In December, I published a long-form piece based on the firsthand experiences of a Syria Telecom insider during the height of the civil war.

  BGP routes belonging to the network of the Islamic Republic of Iran Broadcasting (AS42586) were completely down between ~17:00 UTC on Mar-1 and ~10:00 UTC on Mar-2. Pings (blue line) was already down due to the shutdown. The BGP outage (green line) might be indicative of technical failure (fiber cut, power outage) or cyberattack.
