Hi all,

I use my iBurst connection almost solely for a Cisco VPN connection to our corporate VPN concentrators across the world. I generally use the US-based one and if that doesn't work, EMEA.

This has generally worked fairly well. Starting this morning, it is not working well at all - most connection attempts fail. The few that make it give very bad performance and don't last long.

If I shut the VPN down, local and international performance seems normal, otherwise.

I can't rule out a problem on our corporate network, but since I'm trying with multiple sites with seperate points of entry, it seems more logical to me that WBS is having some sort of problem with their application-aware bandwidth management.

I've been trying to speak to someone there but I'm just clocking amazing hold times instead.

Can anyone shed any light on this?
 
According to what I hear, irc/msn/ssh and vpn have been having trouble. This could be due to shaping of all ports except the norm to an extent that it has become virtually unusable.

Are you capped? Because it would be interesting to note if you aren't, and even more interesting if you are. Because if you are, it would mean that they aggressively shape as suppose to if you weren't. Which makes sense.... to me :D
 
Re cap

I'm on a 3GB cap and according to the most recent counter update (yesterday - I haven't been able to download work email today) I still had some 2.5GB left.

I'm thinking I haven't hit the cap. :)
 
I don't ccare about the bandwidth system.
It's been like this the whole dam day.

Maybe not for you Slimothy but im coming after 6 pm to visit your base station to check the speed and other stuff, If your base station works im going to SEX0R it!
 
Not only VPN affected

I notice now that even some local web sites are not working for me. www.mybroadband.co.za works (obviously <g>), and I see www.ananzi.co.za does too. mail.ananzi.co.za doesn't for HTTP queries, but POP3 to the same host is unaffected. Just spoke to friends who operate Ananzi Mail and they confirmed what I suspected - no problem there.

Sniffing my traffic to mail.ananzi.co.za, I see the TCP establish properly, then my browser sends the request and the remote side ACKs the request packet. Then, nothing, until my side eventually times out and resets the connection. Meanwhile, POP3 flies through normally.

These are the exact kind of problems that I would expect with a troubled application-aware traffic management system. I assume that since I'm having no luck reaching someone at WBS Support on the phone, their lines must be jammed with customers complaining due to these presumably wide-spread problems.

Then why does the "network status report" claim that everything is fine and why don't they back out of the changes?

We've closed our office for the day. We can't work.
