Anyone experiencing DNS issues that is preventing machines from checking into Sophos Central?

We have an issue where PCs are losing connection to Sophos Central and it shows them as not checking in any longer.  Sophos is still running on the endpoints and updating.  Sophos support is saying there is DNS issues that are causing machines to not be able to connect.  

We have it happening as follows:

Both Servers and PCs

It is happening in multiple domains

We have multiple sub estates

We have multiple Sophos tenants

Both servers in the cloud and on prem

PCs both on prem and remote

Anyone else seeing this?
