I am in the Abington CO.

The scenario with Verizon seems to be ... DSL runs fine for months, until they need to add/repair/upgrade equipment. Then stability goes to hell-in-a-hand-basket for a couple of days, weeks or months.

Eventually, they quit "fixing things," and everything runs stable again.

I'm in Evergreen and have seen this pattern repeated now for something like about 6 years (since they introduced DSL into Evergreen). I run without problems for six months or more and then, wham! It happens again.

All of this has nothing to do with PPPoE. I use DCAnet with static IPs (as well as assigned DHCP addresses) and pure IP. The problem is clearly with Verizon's DSLAMs or the ATM cloud. If you can watch the modem, the link light goes out and comes back ... probably DSLAM resets. Other times there are issues with "CO switch reloads" where the configuration for the ATM cloud behind the DSLAMs keeps getting modified.

Needless to say, Verizon never reports any kind of problem or fix to the ISP ... but we watch it happening and then magically "stop."
