[outages] North Carolina TWC IPSEC VPN Issues

[David Palmerton]

We experienced something similar with a customer in North Carolina, also on TWC.

Traffic from their site via VPN dropped about 6 AM, and the VPN dropped. The tunnel was restored but no traffic could traverse it. Traces were inconclusive but it was apparent that there was an issue with transmit/receive or somewhere a route had changed.

Finally routed them to another carrier on our side to resolve the issue.

This was a commercial site, I'll check to see if they use ARRIS modems.

Subject: [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
