Happened to me several times when I had Dry loop DSL & lived in a condo.
I had two lines so I was never hard down but it was still ridiculous. My suggestion is that if you are working from home and rely on the connection then you should be diversifying to cover your ass. It sucks but it's necessary.
Luckily, I won't have to deal with this for too long. I'll eventually be moving back to my home town of Ottawa. Hopefully, I'll find better options there, or I just might create my own mini ISP. -- Watch my future television channel's public test broadcast! »thecanadianpublic.com/live
Ottawa... better options?!?!? Most of the city can't handle more than a few Mbps on DSL and Rogers is not what I call an alternative... Your only other alternative would be a different third party cable provider.
