My .io has been up and down about 25 times in the last 15 hours. The downtime has been about 1.0 - 2.5 minutes each occasion, with a down period of 1 hour 48 minutes at the start.

The latter downtimes look planned, as they are for exact periods (1 minute 0 seconds, 1 minute 30 seconds, 2 minutes 30 seconds, etc)

Here's an extract from the log with timing incase anyone's interested: https://gist.github.com/anonymous/ed37826bc66c23d6c791

What are you using for monitoring / what generated these logs?

Unless your monitor is attempting a connection every, e.g., one second, you're going to end up with the "exact periods" you describe (i.e., presumably your monitor is only attempting to connect once every 30s).

Also, this would be more indicative of a problem with your web host, not the .io root name servers, assuming the TTLs on your RRs are set to > 30s.

The message format looks like something from UptimeRobot.
