Unofficial and Honest Cloudflare System Status

Starting as early as at least 2022-10-26, users may experience a significant performance degradation when enabling HTTP/3 on their sites. Users are advised to disable HTTP/3 for better performance.

Update: Improvements have been made to HTTP/3 performance recently that greatly reduce the impact of this regression.

Scheduled
We will be performing scheduled maintenance in DEN (Denver) datacenter on 2024-06-07 between 08:00 and 12:00 UTC.

Traffic might be re-routed from this location, hence there is a possibility of a slight increase in latency during this maintenance window for end-users in the affected region. For PNI / CNI customers connecting with us in this location, please make sure you are expecting this traffic to fail over elsewhere during this maintenance window as network interfaces in this datacenter may become temporarily unavailable.

You can now subscribe to these notifications via Cloudflare dashboard and receive these updates directly via email, PagerDuty and webhooks (based on your plan): https://developers.cloudflare.com/notifications/notification-available/#cloudflare-status.
