Firstly I'd like to welcome you to the forums and say that I'm really sorry to hear that you've experienced a loss of your phone line.
I've taken a look at things this evening and can see that since your post I can see we did locate a network issue that was affecting you, and this has since been resolved, so I hope your line is now working.
Our systems will flag a potential issue with phone lines, once a certain number of faults are logged from the same area, so it could well be that when you spoke to someone earlier it was the fault report that actually triggered the network technicians. Up to that point we do need to treat each and every fault reported as an individual issue as it may well not be a local issue.
Apologies once again, and please let me know if you're still experiencing an issue.
