Our EU scrubbing center reroutes are dropping traffic at least twice a week. The promised "seamless" BGP diversion to Prolexic is anything but.
Our config mirrors the NA region, which works reliably. The traffic makes it to the scrubbing center, but the clean traffic return path seems to break. We see:
* BGP sessions established with the Prolexic routers.
* Prefixes advertised and accepted.
* A sharp drop in origin server traffic during the attack (so diversion works).
* No corresponding rise in clean traffic post-scrubbing. It just vanishes.
We're left manually failing back to origin, which defeats the entire purpose. Postmortems from last quarter already flagged this as a "known regional peering issue" with no ETA.
Has anyone with EU presence actually gotten this to work consistently? Specifically:
* Which scrubbing center location are you using?
* Are you using GRE tunnels or direct BGP? We're on BGP.
* What's your monitoring setup to validate the full path?
I need more than "contact support." I need the architecture reality.
