Is this web site down for everyone or is it just you?
Down for everyone or just me does one thing, and it does it well. Type a URL into the site, and you'll find out if the whole world is seeing what you're seeing. Easy as pie. You know, eating it, not making it. There's no info on the site explaining exactly how it checks to see if a site is up, but the results appear to be at least as accurate as emailing your friend and asking for a second opinion.
Now, we're big fans in giving products and services a descriptive name. And Down for everyone or just me certainly does that. But if you have any use for this service at all, we suggest you bookmark the site, because seriously, who's going to remember a URL like downforeveryoneorjustme.com?
