They're arguing against the (IMO ridiculous) assertion that 5 months is "short notice." Everyone here agrees an hour's notice would be far too short. Everyone here agrees a decade or five years is too long. So where is the line?

It doesn't mean anyone suggested it should be any of those lengths.

It may take me two months just to figure out how to migrate my services someplace else. I'm hosting 10 accounts worth of email.
