Internet Security Threat Report 2014

Surfers browsing the net using BT connections are having difficulties accessing Web sites because of problems with some of the telco giant’s Domain Name Servers.

The problem, which has been ongoing for at least the last two weeks, has led to a steady trickle of complaints to Web hosting companies from clients complaining that their domains are down. In fact the sites are live and well, as attempts to connect through any ISP other than BT show.

Hosting firm NSDesign tell us that BT has admitted that there’s an issue on its support pages (which can only be accessed by BT customers). However complaints by NSDesign and hosting firm uksecurewebhosting.net to BT’s DNS Team have failed to produce an adequate response.

Our attempts to speak to someone technically knowledgeable at BT on the matter have also drawn a blank.

The problem does not affect all of BT’s name servers, however, as checks by Gareth Ennis, a director at NSDesign, have revealed.

BT DNS servers that do see many of the domains NSDesign’s hosts include:
194.72.6.52 (ns1.bt.net)
193.113.212.38 (ns2.bt.net)
194.72.6.57 (ns3.bt.net)
194.72.9.34 (ns5.bt.net)
194.74.65.68 (ns6.bt.net)

And some that don't see the domains include:
194.72.6.51 (ns0.bt.net)
194.73.82.242 (ns4.bt.net)
213.1.119.97
213.1.119.98
213.1.119.99
213.1.119.100

Ennis tells us that he’s finding the problem doubly frustrating because another server he controls is not affected by the issue.

To resolve the problem he’s considering moving domains over to it even though this would be "a major inconvenience and guaranteed to cause a few short-term
problems". This he says is deeply undesirable but "better this than allow all our BT-using customers to think that we are at fault." ®
