Incident Report for The DOI Foundation
Resolved resolution services were inaccessible for approximately an hour from 00:30 to 01:30 UTC on 2025-05-29.

The issue seems to be caused by some failure of Cloudflare's "Load Balancing" product which is used by to steer global traffic to appropriate backend servers. We have worked around this issue in order to restore resolution services, but were not immediately able to restore full geo-steering functionality or determine why the failure happened. We will add information as it becomes available.

By roughly 03:30 UTC we restored geo-steering by routing through AWS's "Global Accelerator" product. We are still working with Cloudflare to determine the source of the issue.

As of 2024-05-31, Cloudflare has escalated thiis internally, but has still not fixed the issue or provided more information. We are evaluating AWS Global Accelerator as a permanent replacement to Cloudflare Load Balancing.
