Between 10:13 UTC and 10:22 UTC on May 29, 2026, customers using Object Storage (OBJ) in London experienced 5xx errors when trying to access content stored in that location. While attempting to isolate a separate packet loss issue, Akamai sequentially upgraded 2 pairs of routers. The first pair of routers was upgraded successfully, but due to human error the second router pair's upgrade command was executed before the first pair had completed route convergence. This resulted in a temporary loss of routing paths for OBJ traffic in the London datacenter.
The issue was quickly detected via an automated alert, and service was restored automatically once the firmware upgrades and routing convergence completed.
Akamai's Change Management Policy requires all router upgrade activities to be performed in accordance with established procedures and predefined implementation instructions. Akamai will conduct refresher training on the Change Management Policy to reinforce compliance with the required processes and ensure strict adherence going forward.
