My cable connection has been in and out for a week now, and totally down the last couple days. I can only access net from my sister's house, or when my neighbor (not sure which one!) has his/her unprotected wireless connection online.
I can read my e-mail, but not reply. I can read and reply to PMs here. And I was even in chat for a short time last night.
So if you're trying to contact me, expect a delay of at least several days. The cable company should have it all fixed shortly, I hope.
Probably a good thing anyway, I can finish sets and watch more tv, without online distractions.
