Stellate Services unavailable because of Cloudflare Worker KV outage
Incident Report for Stellate
  • Stellate currently relies on CloudFlare services for parts of our offerings.
  • Cloudflare had a global outage of their KV store for ~10 minutes on June 7th, from 6.51 pm to 7.01 pm. They provide a summary of this incident on their own status page at
  • Any traffic that resulted in cache misses or cache passes triggered an HTTP/500 error page during that time frame. Traffic directly handled by the edge cache (i.e., cache hits) was not affected.

    • ~30% of traffic resulted in cache hits and was served correctly.
    • ~70% of traffic resulted in cache misses or passes; these requests returned an HTTP/500 error.
  • We are currently working on a larger infrastructure improvement that will remove the dependency on Cloudflare Worker KV.

  • Additionally, we will review all possible failure points that could make Stellate core services inaccessible (in the event of a third-party outage) and investigate options for additional redundancies for those services.
