Starting at about 9:00PM yesterday my company in Eagle River, WI has been sporadically been losing our SS7 route to the local Frontier tandem (other routes are stable). The outages last from seconds to 5 minutes and then the route is restored. In speaking with a Frontier tech at the tandem they confirmed the issue is not on their end at the tandem but that they are becoming completely isolated and losing all SS7 connections during these outages. They feel it must be a state-wide or at least larger then just Northern WI issue which is why I'm mentioning this to the list. I would be interested to know if anyone has more details on any potential SS7 outages in WI. I've opened a trouble ticket with my SS7 provider but have not received any information yet. Thank you, Nick Paul ChoiceTEL
