13 weeks is way too long, imo. I never powered down, nor had the intention to do so, but I would consider it to be an annoying hassle to wait for 13 weeks.
Then again...
About 18 months ago, my account was hacked. Not too much damage was done, and I was lucky enough to get my account back in a little less than a week. Those were pretty terrifying days, though, not knowing whether I would get back in control in only 7 days. If it wouldn't have worked, and if there would have only been a 4-week power down in place, I would have lost a significant amount...
