Ooops, it was fine last time I looked! It's possible Fitsy has ended up on Hacker News, or some other popular site, resulting in an overwhelming amount of traffic for the small servers the website is deployed on. Or it could be that I just broke the site. Either way, sorry.
Hopefully, it will all be good next time you visit. That or I'll be trying to explain to my wife why we need to sell the car to pay the AWS bill.
