tell us some domains to check. or use some global services like hosttracker - maybe your provider start DNS filtering, maybe there DNS flood to datacenter or your server - check logs. Also if you have own nameservers - check them too

 

[toml]

Maybe something triggered your firewall to block access to/from the peers. Check your log files, there should be some entries about what happened when it attempted to notify the peer DNS servers.
