Lousy, bloated ISP that has lousy outsourced technical support from India. Also subject to busy signals and outages and other problems on dial-up. Earthlink might have once been above AOL and MSN but the quality of their service and support is slipping fast.
After a half-hour on the phone, and survivng the guilt-trip expert who tried to convince me otherwise, I was able to dump Earthlink and switch to a faster local ISP that doesn't outsource it's support to people who don't understand English. I hope they don't keep billing me like they did with other people who cancelled.
