Where does Lindy live?

I figure this one's been on sale long enough to avoid spoilerization, and to be honest I just picked up a huge backlog from my LCS on Sunday.

Two small things bothered me slightly about Mighty Avengers #4, when Extremis-Ultron broke into Avengers Tower to (apparently) assassinate Lindy Reynolds - firstly, wouldn't she be in the Watchtower above the actual Avengers suite? Secondly, if that was the case, should CLOC not at least have put in a token appearance trying to stop Ultron? I find it hard to believe that Sentry's own computer system wouldn't be hardened against EMP or outward attacks - given that CLOC's security system was originally designed to be impregnable even to the Golden Guardian himself!
