Yes, this is very common. You are lucky to even get a working static IP
when they replace a modem. A lot of times they forget to assign one or
assigned one that doesn't work. No, most of the time they won't tell you
the IP changed.

We ran into a strange situation yesterday that I am still trying to
figure out. We have many VoIP customers but yesterday suddenly select
few of them couldn't reach the SIP provider's network from our
network.
I could traceroute to the SIP providers server from the affected
clients' IP just fine.
Well, it didn't say "router hops"... They could mean "AS hops" I
guess. I never trust marketing garbage anyway. It makes my head
hurt.

No, it doesn't. Japan has two systems, both 100v, western Japan has 60Hz,
eastern Japan has 50Hz.
666,624 is kind of odd number, isn't it? That comes out to a

In US, I think everything is 60Hz. But I mean 208v single phase.
(Which is what you get when you combine two 120v single phase legs out
of three phase, I believe. I am not an expert on AC...)

I really want to move all newly installed internal and customer racks
over to all 208v power instead of 120v. As far as I can remember, I

Yes, I understand BFD. The question is, do carriers usually do BFD
with customers? And if they say no, are there other remedies? AT&T
doesn't seem to be even willing to change BGP timers. If anyone have
