perldoc.com has had frequent problems with bandwidth limits and charges, but usually Carlos takes care of those pretty quickly. I asked him about the latest outage a couple of weeks ago but haven't heard back from him. He's a new dad so I suspect he's focusing on other things in life. :)

Other people have mentioned alternative sites, and I'll try Carlos again. If he doesn't want to or can't maintain the site anymore, maybe the domain name can point at one of the other sites (so they have their turn to be victims of their own success :)
