That's never a good thing. We were isolated for ~ 24 hours a couple of years ago and that's something I never want to repeat.
Funny story -- AT&T even called us and said "do you guys know that both your A-Kinks are down"? We replied with the AT&T ticket numbers on the circuits that were down and the SS7 folks said "yeah, we're not allowed to talk to those guys, hopefully they fix it soon". I don't think that escallate button on the ticket does what you think it does.... It was also a complete pain to try to get them to change routing for us. We had a neighboring company offer to give us a temporary link to their switch -- If memory serves that's a F-Link, but AT&T could never get the routing right. Unfortunately, changing SS7 providers wasn't an option. One of the other SS7 providers (to remain nameless) could never actually get their circuits sent to the correct place. This is making me think we should look at getting 2 more A-Links, so we have 4 again...... On Wed, Jan 19, 2022 at 5:20 PM Mike Hammett <[email protected]> wrote: > The links have since come back.
