"One explanation that has gained traction online as users scramble for
answers is the suggestion that a cluster of time servers may have lost
connection with an external source that syncs the time and date."
Haven't seen it, but if people are reporting sudden hour
offsets, on the first Monday in April, I'd bet on a DST implementation
bug that hijacked the system clock on their servers.
This doesn't look like the sort of error you'd get with a free
running clock.
