Given your location I'd guess your prime source of problems would be :
1) Freezer compressors (especially those in the shed);
2) Central Heating/Boiler pumps;
3) Generators;
Noted. Having all known freezers and CH + pumps on a different ring was intended to help reduce this. Think it will help?

Na Fir Chlis, only seen them properly full-on as we have hills and mountains to the north of us which doesn't help. Janet has been much more successful in seeing them.
> FTTP in NW Scotland is going to be the only way to do decent BB as the trenching costs are a lot cheaper and the maintenance costs are a hell of a lot cheaper because it isn't getting blown down/flooded all the time
I just wish I could get some help to make it happen, with BTW or TT or anything wholesaled, so I could stick with the quality ISP of my choice and have a fast and truly reliable service without it costing me a couple of hundred grand. HIE told me to crawl away and die, I wasn't going to get served by a cab this year or next, so who knows. USO? Well we were only joking. What will you do when you want to retire ADSL altogether and have FTTC (capped) as the minimum baseline service?
