Awful latency since 4.0.1 and 4.0.3

Mac Technical Support
Hello, I play from a university campus and since the release of 4.0.1 my latency has been unbelievably, ridiculously high. When I first moved in I had great ms, ranging from 32 to 55, for several months until 4.0.1 came out where I jumped up to 5 digits, 10,000 or more (at once, the in-game indicator said 25,463 ms!) After a few minutes of being in game it lowers to around 5,000 to 8,000, but this is still unplayable. I disabled P2P from the Launcher as I thought maybe that was the issue, no luck there - as well as the usual steps of deleting cache, WTF, etc.

Here's a traceroute:

I really don't know what's going on. I'm really hoping it's not due to the college net, as I said for a long time I had gorgeous speeds. What can I do?

definitely something you'll need to contact IT about, your problem is there.

you using 2 routers? why do I see two DHCP servers? one of them should be set to bridge mode if it's being used as a switch/wireless access point so only one router is assigning IPs.
I have no clue, Omegal =( I'm in a college dorm, I just plug the ethernet cable into the wall and normally go from there.

What exactly can I take to show the network admin to try and get this resolved?
this traceroute show him hop 3, the problem is clearly right there with highly unstable latency, an 800ms hop in your local network is a major problem, unless you happened to have heavy upload going on at the time such as a torrent.
No, no upload on my end. But is this something that's even fixable? There's probably other people using the same connection, right? This network stuff is over my head o_o
just show that traceroute to an IT guy as well as give him approx times of those problems. he will know what to do with it, whether or not they actually do something though depends on them.
Alright, thank you. =)

If, there's nothing that can be done, are there any alternatives? Like, can I get to the internet through some other means than the university provided net?
If you are nice enough to your network admins, they may also open some ports for you to resume playing better. Try bringing them a present and ask them to do this:

In order to resume functionality of Blizzard games, your network administrators will need to allow traffic over ports 1119, 1120, 3724, 6112, 6113, 6114, and 4000 for both TCP and UDP, as these ports are used and reserved through http://www.iana.org/; the port listings can be directly found at http://www.iana.org/assignments/port-numbers.

Most times they are nice enough to do this.

Do you love Boomkins? Sure we all do!
Wait I mean, take a moment to let me know how I am doing. http://www.surveymk.com/s/RF8K3KG
Why is this a problem on my university campus now and was not a problem earlier?
you'd have to ask them.
