Summary AI Generated
Tailscale experienced a 7.8-hour incident preventing the issuance of new TLS certificates for MagicDNS hostnames, blocking manual certificate requests and the creation of new Serve and Funnel domains. Existing certificates and active Serve/Funnel services remained operational throughout. An initial fix was deployed but caused an error rate spike requiring further investigation, with a second fix ultimately resolving the issue.
We are investigating a problem which is causing problems with issuing new certificates for MagicDNS hostnames. This problem affects manual certificate issuance and the deployment of new services through Tailscale Serve and Funnel.
Existing certificates and services currently exposed by Serve and Funnel will remain unaffected as long as the current certificates stay valid.
