Presumably many institutions would have other sources of pricing data too - I know this is the case in many sell-sides, not sure about everywhere else. I've worked in a few sell-sides and you see bloomberg screens all over the place, but usually alongside front office trading systems like Fidessa which are powered by direct feeds a lot of the time. Probably a much bigger issue for everyone who doesn't have exchange connectivity, but you'd also hope they have some sort of fallback for exactly this scenario. I.e. reuters or something.
