Hi @amplex,
That IP was removed from the pool at 2023-08-15 14:42:29 (UTC) when it wasn’t responding. When it came back online around 14:59 it had an unsynchronized time signal (“leap=3”) and remained out of the pool.
A couple recommendations:
- Don’t use a single IP to get the time
- Don’t hold on to a DNS result for an excessive period of time
- Check the leap flag, when it’s 3 the clock isn’t synchronized
