Major Packet Loss through Level 3 Backbone
I am experiencing major packet loss for any traffic that is routed through "Phoenix1.Level3.net" as shown in the below screenshot. There are a handful of sites that basically won't load or are simply unusable due to the packet loss/slow speeds. This is definitely not an issue specific to my modem or router, as it happens on both the residential connection at my house AND an entirely separate Cox Business connection at my office 3 miles away. I have tried several different computers, bypassed all routers and switches, and rebooted modems. 100% an issue with Cox and/or Level 3.
I manage a web site that is hosted on WebHostingHub.com and I can't even access that site without switching over to a VPN or using my cellular connection. Extremely frustrating. I opened a support ticket with Cox over the phone yesterday but still haven't seen any improvement. Again, as soon as I activate a VPN (which routes the traffic through a different backbone), the issue goes away and the websites load as expected.
Are there any known issues with Level 3/CenturyLink at the moment? Or any other issues with the Cox network in Phoenix that would be causing this?
