The building has scheduled maintenance later tonight on the A leg of power from the D/C power plant. A customer in the building, do not know who, or where, allegedly blew the power on both the A and B legs of the D/C (direct current) power plant that services the fiber MUX gear handling: OC12c connection to Qwest's qwest.net backbone DS3 connections to Qwest ATM network for DSL DS3 connections to Qwest handling PtP T1 connections DS3 connections to Qwest ATM network for Frame-Relay T1 Because of the pending maintenance the building had scheduled, an electrician is already on-site and work at finding the break in the power has already begun. I have been in contact with the building and a fuse (D/C power still uses fuses) has been replaced in one spot, but another needs to be replaced as well. I do not have an ETA for service availability but, as I said, I am in contact with the building. The MUX itself is fully redundant with power and fiber from Qwest, and using both the A and B legs for power should have offered the power redundancy required for this gear. How both legs went down because of one 'something' just should not occur. ipHouse uses A/C (like what you have at home, just a lot more of it), while many telephone companies (Qwest and others) use D/C to power their telecommunications gear. While this outage is happening, we have lost 1/2 of our Internet connectivity, all DSL service, and all T1 connected customers. The Qwest MOE (metro optical ethernet) service is unaffected, as well as power and connectivity to the data-center itself. I will send another message when I know more.
