I run a VPS using ubuntu 14.04 server. Recently I have been receiving multiple messages on my auth.log of the form: eventdns: All nameservers have failed [code] eventdns: Nameserver 8.8.x.x:53 is back up These come at a rate of about 150 -250 per day. The server neither shuts down or exits software. Can anyone give me an estimation of what is wrong. L Brandt
