I have the Same problem
Hi guys,
There was a DNS issue earlier in the day which has been resolved - but unfortunately due to how DNS works, replication may take some time to hit your DNS server.
Right now there is a workaround available in using Google's Public DNS servers - please follow the instructions here which should help you get back up and running:
