Fog knocks out North Tipperary telephone network..

I have been experiencing continuing problems with our home-phone lines.
For the last 4 months both lines would go completely dead somewhere between 4:00 & 4:30 in the afternoon. No incomming or outgoing calls, no dailtone, nothing...
Then two weeks ago both lines died on Friday and it took Eircon 4 days to repair the fault. Less than a week later it happened again. This time the fault was repaired within a day. Only to re-occur less than 24 hours later....
All in all both lines have been out of action for most of the last two weeks. To be honest Eircom have been very pro-active by sending people to my house and by calling me to ask if everything was OK. However they have not been able to pinpoint the cause of the problem.
Today I got the best call off all: an engineer called to explain that the backhaul from the local exchange was through a radiolink and that the recent fog might have been causing the problem.
So there you go: fog can knock out the Irish telephone network.
It's back to two cans and a piece of string I guess....
