    We're seeing traffic coming back towards normal limits, as Cloudflare implemented a fix for their DNS servers.


    We'll continue to monitor the situation.

    Cloudflare's DNS servers (1.1.1.1 and 1.0.0.1) seem to be having major issues:

    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 towards 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 their DNS servers so that your server regains full DNS resolution capabilities.
