Leitrim is officially one of the worst counties when it comes to broadband speed.
That’s according to the website switcher which has compiled a year’s worth of speed test data for home broadband; almost 27,000 tests.
Dublin has the highest speeds.
Sligo and Donegal have much faster speeds than Leitrim and also fare better than the nearby counties of Cavan, Roscommon and Mayo.
