I think it's just you, probably recency bias. I recall the days of Gmail being globally down for hours, more than once (3 times, IIRC), back in 2009.
(Yes, I know they discontinued it, but I haven't seen the service "over capacity" in some time. I say this as a casual web user of it, not an active account holder or app user).
Facebook had an October outage.
This happens quite regularly with distributed and complex systems.
