Craigslist won't load on my laptop,

Last couple of days CRAIGSLIST will not load all I keep getting is "Server Not Found..." . I think it only loaded on Tuesday Night for about an hour or two then it went down again!  I tried using Internet Explorer, Chrome, I even thought that maybe there was something wrong with my two laptops.

I depend on CRAIGSLIST for my Job and this is not good!!

It is going to be a fuul week that they (CRAIGSLIST) IS DOWN COMPLETELY!!!
