Welcome to the forum, so sorry you are having DNS problems, we will try to help.
We had a CMTS fault in your area ref F003757609 where some customers were unable to obtain an IP address. We think we have fixed this yesterday and are monitoring things to be sure. At the moment you have a valid IP address, phew
We have no known problems with our DNS servers. Sometimes the default error on a device is to say unable to contact DNS server when the entire internet connection lost such as a faulty IP situation and it is not specifically a DNS issue, I wonder if that is what has happened.
Are you able to ping our DNS
Primary DNS: 220.127.116.11
Secondary DNS: 18.104.22.168
What happens if you go back to using ours? Please give as much detail as you can.
can confirm it came back on around 6PM yesterday, and didn't have any dropouts whilst using it last night.
as you say it was a fault with entire connection, so although I had changed to OpenDNS and Google options to test, because they didn't work either I reverted to auto select, so will have been using your servers.
can now consider this closed, just frustrated that the online service status doesn't give any details as to the actual problem, just a general statement.
the fault said phone, tv, and broadband yet we only lost internet and Tues. 5.30pm whereas we didn't lose connection until 1am on Wednesday.
