Yes, I almost took half a floor of 365 Main back in 2003-2004, and didn't due to their (at the time) tenuous financial situation and thus being underresourced on everything. That and there being ~no carriers in the building at the time. For SF colo, 200 Paul remains a superior choice, although some floors have had problems, and it's a totally conventional design.
But the hitech UPS was a weak link. When they sold all their facilities to someone else (DRT), that fixed most of the other issues.
