Narrative:

Pushback from all X gates at phl is 'advise ground.' we did this, but for unknown reason, push crew pushed aircraft back partially onto ramp taxiway directly behind gate xaa. As soon as we realized this, we informed ground control, who was aware already. Recommend that gates xaa, xab, and xac require clearance, rather than 'advise' ground prior to pushback.
