Norwich City at Carrow Road and the East Anglian derby with Ipswich Town give the city its main rivalry, contested across a region with very few other senior clubs. That sparseness is the defining feature of football here: Norwich is genuinely isolated, with no other professional club nearby, so the city and much of the surrounding county pull in one direction. Norfolk is also one of the more rural counties in England, and connection quality outside the city varies considerably more than it does in the urban north or the south east. Between a club that spends time in divisions with limited coverage and a variable rural broadband picture, testing at home before paying is sensible here.
Norwich has reasonable coverage across the city and out through Thorpe St Andrew, Sprowston and towards Wymondham, but Norfolk beyond that is one of the more rural counties in England and connection quality varies considerably, with plenty of areas still on slower services. The city has a substantial student population and a historic centre with conservation constraints on a good deal of the housing stock. Being genuinely isolated, with no other professional club nearby, the fixture question is unforgiving here in the same way it is in Newcastle. Test both halves at your own address: whether the division is covered, and whether your line actually holds it.
