I’m beginning to hate nLayer

Update: spoke too soon, they finally got back to me, so maybe it will go somewhere 🙂

Update the 2nd: now that they finally got to my ticket, they seem to have taken care of it very quickly; the issue has not happened since they tweaked something last night! 🙂

For the past few weeks I’ve been having constant disconnects between me and a server I’m often connected to. (Up to 20 disconnects a day, often grouped together, getting very annoying)

My debugging leads me to believe it’s an issue with some of nLayer’s routers, but so far their support department has completely ignored my messages…

Here’s my tests:

As you can see, the connection always breaks off at xe-0-2-0.cr1.dfw1.us.nlayer.net (69.22.142.22) and xe-2-2-0.cr2.ord1.us.nlayer.net (69.22.142.2)

Why they can’t fix/replace it is beyond me, or at the very least respond to even say it’s been passed on to the actual network guys – its been weeks since the issue started, and almost a week since I opened the support ticket…

Bleh, just wanted to rant a little – if anyone knows more than I do about networking, am I wrong about what the info indicates? Could an issue outside of nLayer’s network trigger such a consistent disconnect in traceroute/tracepath?
