Server Agent Metrics

Update timeline

  1. identified Nov 18, 2025, 03:08 PM UTC

    Cloudflare's DNS servers (1.1.1.1 and 1.0.0.1) seem to be having major issues: https://www.cloudflarestatus.com/incidents/28r0vbbxsh8f https://x.com/Newspicel/status/1944880481704796373 This issue affects our Server Monitoring Agent installed on servers that use these DNS servers. Since these servers cannot resolve any hostnames at this time, our Server Monitoring Agent cannot send any metrics to our platform. Resolution: Use diverse DNS servers on your servers (i.e., a mixture of Cloudflare and Google DNS servers), or wait for Cloudflare to fix its DNS servers so that your server regains full DNS resolution capabilities.

  2. monitoring Nov 18, 2025, 03:09 PM UTC

    We're seeing traffic coming back towards normal limits, as Cloudflare implemented a fix for its DNS servers. We'll continue to monitor the situation.

  3. resolved Nov 18, 2025, 03:10 PM UTC

    We're now seeing traffic back to normal, even though Cloudflare hasn't yet marked the issue as resolved on their status page.
