Re: UUNET connectivity in Minneapolis, MN
I certainly understand why utility power goes out and that is the reason why MCI loosing power confuses me. I am pretty sure that someone at MCI also realizes why the blackout happens and how fragile things are. It is irresponsible for a Tier 1 infrastructure provider to not be able to generate their own and have large chunks of their network fail do to the inability to power it. I bet you every SBC CO in the affected area was still pushing power out to customer prems. Unless there is some sort of crazy story related to why a service provider could not keep the lights on, this should have not been an issue with proper operations and engineering.

RE: UUNET connectivity in Minneapolis, MN
Yes that is an exception... not what happened in this case You can come up with a lot of valid exceptions... There are many reasons why a Tier 1 provider does not stick all its eggs in multi-tenant buildings... smart things can be done with site selection. I am not saying ever customer needs to keep their network like this... but the really bug guys at the core of their network yes.

The building where one of our nodes sites got hit with an electrical fire in the basement one day, the fire department shut off all electrical to the whole building including the big diesel generators sitting outside the back of the building so all we had was battery power until that ran out 6 hours later. How do you prepare for that? Geo. George Roettger Netlink Services
Re: UUNET connectivity in Minneapolis, MN
we had a loss of comercial power(coned) in the downers grove terminal. terminal is up on generator power now. that seems to map to the internal firedrill as well, anyone else hit by this event? Electric utility had a sub-station burn up. resulting in a medium-sized geographic area without power -- something like 17,000 residences according to news reports (no numbers on 'commercial' custeomrs provided). ATT has a facility in the affected area, and were also without utility power. Rumor mill says that Sprint had a (moderately small) number of T-3 circuits affected, as well. ATT must adhere to some diffrent engineering standards; as well devices we monitor there were all fine no blips... but all of the MCI customers we have in IL, MI, WI, MN all had issues... Power went out at 4:30 ish and ckts all dumped about 8:30 pm... Then bounced until 6:30 AM this morning. Not sure I understand how on earth something like this happens... power is not that confusing to make sure it does not stop working. JD
