I think I've seen computers with more uninterrupted uptime than that, even if servers. Or at least approaching this figure.
Perhaps you meant ‘quarter of a millennium’ or something like that.
I know Enterprise customers require extreme backward compatibility, but it must be a fairly small number who are still running legacy code written in 1771.

I stand corrected, and awed. Thank you!
I had the good fortune to see the Babbage Engine in action when it was at the Computer History Museum. Only got a few photos, but here they are (plus an unrelated photo of a core memory plane):
