Belfast has the densest club football scene on the island. Linfield at Windsor Park, Glentoran at the Oval, Cliftonville at Solitude and Crusaders at Seaview all sit inside one city, and the Big Two meetings between Linfield and Glentoran are the fixtures people plan the day around. Windsor Park also hosts Northern Ireland internationals, and Ulster rugby draw big European nights at Ravenhill. On top of the local game, Belfast has substantial Celtic and Rangers followings, so Scottish football matters here in a way it does not in Cork or Galway. Antrim GAA add a further layer. The practical problem is that the Irish League, the Scottish Premiership and European rugby have rarely lived on the same service, which is exactly the thing a trial lets you check in an evening.
Belfast has some of the best full-fibre availability anywhere on the island, and across most of the city, from Andersonstown to east Belfast and out through Newtownabbey and Castlereagh, bandwidth is not the limiting factor. Housing is what matters here: large parts of the city are terraced or subdivided, a great many households rent, and anything requiring a fixed installation is awkward or not permitted. Belfast also has two universities and a correspondingly large short-lease population. The thing genuinely worth testing in this city is breadth rather than speed. A household here might want the Irish League, Scottish football, the Premier League and Ulster rugby, and the useful 24 hours is spent checking whether all four are actually present rather than assuming from a channel list.
