[outages] North Carolina TWC IPSEC VPN Issues

I have a customer that, last friday at 2AM, they lost VPN connectivity to about 6-10 of their sites in North Carolina Raleigh/Charlotte area. The only common thing with these sites is that they are all Time Warner Cable and have ARRIS modems. When we look at our VPN end-points, we only see IPSEC sent and not received. Their head-end has 600 other VPN tunnels on it with no problems, it is just the ones on TWC in that area. Is anyone else having issues or know of an issue there? Thank you, Jeff
