[VoiceOps] TNS SS7 Outage

[Mike Hammett]

Currently the story is that there was a power supply issue in Chicago. 


Okay, so Chicago went down. What about Ashburn? Just how big was that power supply? ;-) 


I know TNS has more facilities, so I'm going to try to get another link out of them gratis.

The links have since come back. This is the second major failure of TNS within 6 months. No RFO yet, but I will certainly be on them for some detail. 


My Metaswitch support rep verified that (pardon my lack of using the correct terminology, I'm not that familiar with it) our SS7 links never actually went down, it just lost connectivity beyond that. Sorta like my BGP peer stayed up, but I lost the global routing table behind it.

Does anyone have any information on the TNS SS7 outage going on now? Both of our A-links go to different facilities (Chicago and Ashburn) over different VPNs (which are up). 

TNS has acknowledged that it's a carrier issue. That they're investigating.
