there were some DNS issues today because the DNS load balancer failed in a spectacular (and unanticipated) way which caused the domains serving the VPN to expire. It took us some time to debug the issue and roll back the git and redeploy all affected zones. All DNS servers should be back and operational again. If you are still having issues try to clear your DNS cache.
We are sorry for the inconvenience this might has caused.
