- investigating Jun 20, 2025, 12:41 PM UTC
Customers connecting to our services in Slough over Cogent transit may have seen instability over the last 15 minutes or so. We have temporarily shutdown sessions with Cogent to alleviate any issues. Those on-net or reaching us over peering sessions (which is the majority) and other ultimate transit providers, or reaching other availability zones over Cogent have been unaffected. We strongly encourage all customers to connect into us directly wherever possible.

Cogent have confirmed issues on their network. Our sessions with them remain shut down to prevent impact. We will continue monitoring and will only reintroduce routes for Cogent in Slough once we are confident their network is stable.
