My partner has had no TalkTalk broadband connection since yesterday afternoon (July 26). I went on the downdetector.uk website and found that TalkTalk is down all over the country, so I informed him (I'm in Sussex and not affected by this problem). Thank goodness for downdetector. I cannot think why TalkTalk cannot put up an announcement on its website.
I have left a comment on its website but it was difficult because it assumed you wanted information about a product or had a problem with your computer. There was nowhere for people to report outages.
He did manage to get through on one of the help phone lines finally and was told TalkTalk was going to work on the problem this evening. Let's hope they resolve it as many people must be badly affected.
