in England I've seen big corporate services like Dropbox and Sage Drive (used for accounts systems) made inacesssible or intermittent due to a misconfiguration at an ISP, and even that took about 2 weeks to resolve (and the ISP logged the ticked immediately) - I had to get some of the Accounts department staff to work in a different office next door - ironically this was connected to the *same* ISP but via a different network backbone!)
