There are several Clients that are affected by the current DNS (Domain Name Services) outage that is ongoing at the time of writing.
This seems to be limited to DNS hosted with the provider “Discount Domains” and this is affecting inbound remote access, some VPNs and preventing some emails being received. There maybe be other impacted services beyond these.
Our support team has checked in with “Discount Domains” and there is no ETA as of the time of of writing.
