On my work computer, I cannot access Craigslist.org even though I could yesterday, for most of the day, and can access t he site on my smart phone. When trying to log on to Craigslist, I get an error message of 'problem loading page' 'server not found'. I can access other websites just fine, I only get the error message when trying to access Craigslist. This site is in my 'favorites' and that is the way i access it everyday. Today, and most of yesterday, it's not working. ????
