Anecdotally, I've noticed that management tends to consider interruptions more acceptable for anything related to web development. It's usually not as bad for the web dev team to slip their schedule as for the hardware team or the legal department or whatever, so interruptions happen more often. I was briefly embedded in such a team and that aspect drove me nuts. You really have to enjoy being essentially a point of contact as part of the job.
