OGO Security - Outgoing IP temporarely added – Incident details

At 13:53 CET a network misconfiguration affected the cluster OGO EUW1 resulting in a portion of the outgoing traffic using an IP that was not part of the ranges assigned to this cluster. The customers sites who have implemented an origin IP restriction based on OGO EUW1 assigned ranges were impacted :For those sites, about 20% of the users of the site were denied access because the IP presented by OGO EUW1 was out of official assigned IP range, and thus, rejected by the origin.The misconfiguration was solved at 14:10 CET.
