My experience was that a lot of internal tools were tremendously janky. The awful system used for filling out compliance questionnaires for audit often had 10+ second UI latency when saving text fields. The perf tools often broke right when everyone had to use them all at the same time. I don't know if they every built a proper replacement, but for at least half a decade the Baggins Roster UI (internal backend for things like Google Groups and such) appeared to have been an abandoned summer intern project.
