Now Broadband is ordinary domestic broadband, and the price and the service reflect this. So they aren’t set up to compensate you for more than the loss of some leisure-time use of the internet.
The elephant in the room of WFH is that you don’t get business-quality broadband for domestic broadband prices, and if you want an unburstable service, with 4G/5G fallback if the fixed line goes out, say, then look to a company like Zen Internet for it, and be prepared to pay their prices 😢
Two lines isn’t the answer, as I have found even in professional use - sooner or later, two lines, unless linked to two separate exchanges at vast cost, will wind up going down the same piece of affected cable, and both will be down. And indeed, for an area outage, even having separate exchanges is no guarantee they won’t go down together.
The backup line has to be via mobile internet, to have a decent chance of being unaffected by any given outage,
I have BT 500Mb FTTP, of which in practice I can get up to 360, with mobile continuation through EE mobile if the landline goes down, as I require 24/7 availability to my employer, week on and week off.
It doesn’t come cheap, but they make a contribution 💷
Who do you move to, AAMOI?
