TE slow for anyone else?

Since Monday I had had TE time out when clicking around the forums, seems to be about 30% of the time. Is this on my end or are others seeing this?

You're not the only one. I've been experiencing the same problem.

No issues here, what dns are you using?

docrice

I've been seeing this as well. Other sites would be fine, but the lag on this one has been noticeable.

Interesting. I wasn't seeing this problem until about 10 mins ago. The only difference is that I moved from my desktop which I use Mozilla as browser on Linux to my laptop which I use Chrome on Windows 8.1. The slowness seems to only happen on Chrome. Just a thought...

Same here, a little slow for me too on this side of the world.

That would be "Abbots Internet" doing that. :P

I had it completely time out on me the other day. Maybe someone is practicing Pen Testing??? :O

Doyen

I've had that same issue, but only when I am using my college's computer since Monday. When I am at home, I have not experienced those issues.

If you saw the state of the Internet in general in my area, you'd want to cry, it's that bad. No NBN, no ADSL, just sh1tty wireless.

Webmaster

Thanks for the PM Paul.

I haven't noticed any major performance issues with the server today or this week while I keep a close eye on it. Being that it seems it affects some and not others, it's however possible there are/were some pops of our CDN were busier than usual (images and large scripts are loaded from those), you can tell if that's the case if it times out on cdn/images.techexams.net instead but does load the www.

I just tried some performance and response tests from several locations and it looks ok, as usual that is. I will take a closer look tomorrow early, but in any case, if it's actually timing out rather than an occasional delay please email me tracert (to www. and cdn. ) output (webmaster at techexams.net).

I have been experiencing lots of issues with the site in the last 2 days.

Every 2nd click causes the page to not respond.

Admin: I have done a wireshark capture during which I experienced a drop. Looks like my machine is doing a whole heap of TCP re-transmissions.

I am using Chrome with Windows 8.1

Tried with Firefox, had no issues.

EDIT: I did more testing. Firefox performs the same as Chrome.

Cheers

This is the error that comes up, probable about 1 in 5 times I hit a link

Yeah I have been getting that as well

MSP-IT

Having the same performance issues as well. Different providers/browsers across the city.

Our proxy server is throwing the error.

Further analysis.

I noticed it was really slow last night. It is a little faster to respond now, but not 100%.

jibbajabba

Yea, kept getting nothing for quite a while. I noticed that every time I had this issue, some google ads tried to load in the background .. But that might just be a coincidence ...

xnx

Are you at a university or do you work at one??

Not quite a University and in late 30's a bit old to still be studying at one. I work at a partly Publicly funded scientific research institute (see my linked in profile for more info), but we do have Academic status. Hence the reason we run on Janet which is what I assume gave it away.

N2IT

Yeah I am experiencing time outs.

I'd say every 5 tries it's bombing 2 times.

Webmaster

@N2IT: if you are experiencing time outs atm please send me tracert output (email or pm).

Thanks for the feedback and PMs so far. Shortly after my previous post our host posted they had network issues ( https://twitter.com/softlayernotify ) but I just heard that shouldn't have affected our server... It's a little hard to track down because it seems to work most of the time and not affect everyone including myself. I suspect there is a network problem (being that our server is running smoothly) and hope to find and solve it today. Currently have someone at my host investigating as well and I hope to have good news soon.

xnx

Yep, even without the DNS names i'm familiar with the JANET 146.97.0.0/16 block

DevilWAH

You work in janet or at a connected institute?

xnx

I wish... I got this of people that work/worked on JANET- I've only studied JANET as a part of real world network provisioning / QoS at University. I've got some more diagrams but i'm sure they would be traceable to source..

DevilWAH

Janet is cool, not just are they a great ISP, dealing with some of the biggest scientific data in the world. But they have a conference each year with IT engineers from all of the top university's and research institutes around the world. We all sit around tell each other how we use the network and the kind of things we are getting up to and how we would like to see Janet moving forward.

so unlike in the Private sector where people try hide what there doing from each other and the ISP is jsut a service provider, we get to sit down for dinner with them each year and have a pint or two.

xnx

These are a pretty good set of documents for those that manage campus size / educational networks

I noticed everything was slow since the start of this thread (particuarly the "Today's Posts" link) but everything is super fast again, I just thought I'd mention it's like it is back to normal...

DevilWAH

It does seem to have improved I have been clicking around for about 20 clicks and no issue so far. Looks like the issue has either been fixed or disappeared. Either way thank you to every one who has been looking in to it for us.

Webmaster

Hey thanks for posting guys. We're still working on the issues but made some progress and changes that should make things go a little smoother. It may get worse again a couple of times before we really solve the problems permanently.

Essendon

Thanks Johan, back to normal for me too. In fact, it's really snappy now!
