Is anyone else experiencing issues with return traffic to the Verizon FIOS network? I've noticed that return traffic from our network destined for Verizon FIOS customers either hits 0.xe-3-1-1-XL4.CHI13.ALTER.NET or TenGigE0-2-0-1.GW5.CHI13.ALTER.net and dies off completely or continues on through the Verizon network and experiences issues in the Dallas TX, Newark NJ, or New York FIOS network portions. I've attempted to route traffic out different providers and this appears to alleviate the issues but I have noticed the issue occasionally cropping back up and it appears to be at the point where the other provider hands off to the Verizon network. I've reached out to Verizon and they've been somewhat quiet with occasional replies that they've identified a 'bad path" or replaced a "provider edge card" on a device. I've recently received an influx of complaints with Verizon FIOS support claiming no issues on their network and that it's other networks experiencing issues. Found a couple recent threads that appear to be experiencing similar issues. http://arstechnica.com/civis/viewtopic.php?f=3&t=1247379 http://www.gossamer-threads.com/lists/nsp/outages/51139 Possibly affected Verizon prefixes 173.57.0.0/16 173.71.0.0/18 70.104.26.0/20 71.97.0.0/17 72.91.0.0/16 108.30.0.0/16 108.34.128.0/17 108.35.0.0/16 108.5.0.0/16 98.113.0.0/16 96.225.0.0/17
