We've recently observed some unusual large-scale routes appearing on the internet (see image), involving the following networks:
AS393232: Comcast Cable Communications 🇺🇸
AS36429: Charter Communications 🇺🇸
AS41128: Orange 🇫🇷
AS13335: Cloudflare 🇺🇸
AS17072: Total Play Telecommunications 🇲🇽
AS270118: Soluciones, Analíticos Y Servicios Team (Stratosphere Technology Latam) 🇲🇽
AS199524: Gcore Labs 🇱🇺
The label "path (fixed)" indicates that identical paths were observed by several probes across the internet. This strongly suggests that AS199524 is the central pivot point behind these announcements.
While the first four paths have since disappeared, the most recent three remain active. ⬇️
