DOI proxy service was unavailable for a few hours due to a “widespread BGP routing leak” today which affected especially Cloudflare [1] and many other internet services. DOI services were impacted between 10:41 (UTC) and 11:00, with further partial failures until 11:24, followed by another brief failure for a few minutes at 11:55. It is possible there were other intermittent failures for users that are not reflected at the monitors; Cloudflare did not mark their incident as resolved until 13:02.
