Heads up for folks doing DNS validation against Cloudflare

DNS propagation may be delayed during a maintenance window coming up on 2022-09-07. Just got an email with the following:

Cloudflare will be carrying out maintenance work to make the DNS records database more performant and increase its availability. During the maintenance window, updates to DNS records might be delayed. This includes other services that may create DNS records on your behalf like Spectrum, Load Balancing, or automatic TLS certificate validation.

Cloudflare’s edge will continue to proxy requests and Cloudflare nameservers will continue to respond to DNS queries. Only updates to DNS records will be affected during this time.

Window start : Wednesday, 7th September 2022 - 16:00 UTC

Window stop : Wednesday, 7th September 2022 - 17:00 UTC

Expected impact :

  • Elevated DNS record propagation time
  • Elevated API response time for DNS record change requests
