The GUCP (Ground Umbilical Carrier Plate) that leaked is part of the
External Tank/Launch Pad interface. The External Tank is brand new
each mission. The launch pad side was redesigned last year after
smaller leaks. All launch pads have GUCPs or something similar.

Last time this happened it was due to a misalignment on the ET
attachment plate for the GUCP during manufacture.
