Mulley managed to get his hands on a list of Eircom's DSL-enabled exchanges, and asked if I could work some Google Maps mojo on it.

Update: then he sent me a list of all the exchanges, not the 35% which are enabled. We've just fixed that.

This is a screenshot of the resulting map, with a 4km-radius circle drawn around each of his points.

If you're extremely patient and don't mind your browser either crashing without warning or complaining a lot about how long the Javascript's taking to execute, you can see the Google map it was snatched from here, and there's also a version with the circles enlarged to 5km.

I prefer the 3km version because it's more accurate. Outside that radius any connection you'll get will be rate-adaptive and is not guaranteed beyond 128kbps - which hardly counts as 'broadband' in my book. If you can get it at all.

You can see that, basically, if your telephone area code doesn't end in a 1, it's a crapshoot.
