Plusnet, the internet service provider, has suffered a "Major Service Incident" which started on Wednesday night. The outage continued until this morning.
Users are complaining that they cannot visit a number of websites. Some were able to mitigate the TITSUP by changing their DNS provider.
A Plusnet staffer told its community forums:
We are in the process of investigating this now. I will provide on this thread, and our Twitter pages as soon as I receive more information.
Our systems where we provide the service status are also unfortunately down, but I will endeavour to get one up as soon as I have the facility to.
Really sorry for the inconvenience caused.
