Cork is a hurling county first and everything else second. The Rebels in the Munster championship is the fixture the year is built around, and Páirc Uí Chaoimh on a summer Sunday is a different scale of occasion to anything else in the county. Underneath that, Cork City play at Turner's Cross, which is one of the better atmospheres in the League of Ireland when the ground is full. Munster rugby matters here too, with Musgrave Park in the city and the bigger European nights up in Limerick. That combination is awkward for anyone buying telly, because hurling, League of Ireland soccer and European rugby have historically sat with three different broadcasters. Testing all three inside a day is the quickest way to find out what you would actually be giving up if you switched.
Cork city and Cork county are two different propositions. Douglas, Bishopstown, Ballincollig and Blackpool are well served and 4K is a reasonable expectation. Head out west towards Dunmanway or the Beara peninsula and the picture changes considerably, with plenty of households on slower services or waiting on rollout. Carrigaline and the harbour towns sit in between. The city also has a large student population around UCC and MTU on short leases where installing anything is impractical. If you are in the county rather than the city, run the trial at your own address before deciding anything, because a neighbour's experience three miles closer to town is not a reliable guide to what your line does at nine on a Saturday.
