Subject: DNS Problems - NEW (Ref 36380)
We are currently investigating a problem which could affect customers' Internet connectivity.
Whilst customers will be able to connect fine - they may experience intermittent difficulties accessing webpages, sending and receiving email and using other Internet applications. This is due to an issue with failed lookups and timeouts via our DNS servers.
We are currently investigating this issue and will provide an update later on today.
Kind Regards,
Liam Martin
