著者: Cloudflare
2026年8月24日 21:00

THIS IS A SCHEDULED EVENT Aug 24, 12:00 - 13:00 UTC

Aug 4, 07:31 UTC
Scheduled - Cloudflare will be performing scheduled maintenance on the databases that store SSL/TLS certificates, certificate orders, and related configuration. During this window, new certificate orders and renewals may be delayed or fail, and changes to SSL/TLS settings via the dashboard or API may experience elevated response times or temporary failures. This includes operations for Universal SSL, Advanced Certificate Manager (ACM), Total TLS, Custom Certificates, SSL for SaaS (custom hostnames), and Origin CA certificates. Cloudflare's edge will continue to proxy traffic and terminate TLS as normal, existing certificates will remain active and unaffected. Only new certificate operations and configuration changes are affected.

Cloudflare Workers Runtime API issues

著者: Cloudflare
2026年8月4日 16:12

Aug 4, 07:12 UTC
Resolved - This incident has been resolved.

Aug 4, 07:00 UTC
Monitoring - A fix has been implemented and we are monitoring the results.

Aug 3, 15:21 UTC
Identified - Workers runtime: Temporal global exposed with an incorrect clock

Since 2026-07-30, the Workers runtime has exposed a global Temporal object that was not intended to be available. Its clock is wrong: Temporal.Now reports 1970-01-01 rather than the current time. Date and Date.now() are unaffected and report the correct time.

This can affect Workers that install a Temporal polyfill only when no native Temporal is detected. On those Workers, the polyfill stopped being installed and time-dependent logic began computing against 1970 — for example, tokens minted with an issue time of 0 and an expiry in 1970, incorrect TTLs, or incorrect date arithmetic. No error is raised when this happens.

Aug 3, 15:13 UTC
Investigating - Cloudflare is aware of an issue with the latest Workers Runtime API release that exposes native Temporal with clock stuck at epoch 0. Updates to follow.
