The servers should have definitely been prepared for the increased load. Perhaps I'm overly optimistically using the plural form in this case. Truth to be told I can only assume this was done in a short burst, given my limited sample of (hopefully ever narrowing) circle of people who use Atlassian products. But would distributing the bulk-mail over an hour (two, three) using a randomized sample of their customer base really made a significant impact to security or their support? I wonder how I'd do it, really, if let's say, beefing up my infrastructure for some reason isn't an option.
