Where oh where has my dial-up gone?

Ok, so for the past two days my Earthlink dial-up has been giving me nothing but busy signals. Checking the Network status page hasn’t yielded any information in my area (maybe I’m the only one here using Earthlink dial-up?) and the first response from support just told me to try the three numbers I’ve already been trying. Gee, thanks.
No net access from home, so I have to get my fix at work. But I haven’t been at my desk much lately, so there’s not much of that either. Hopefully there will be some resolution by tonight or the weekend.
