darn.... I can't get to SU, SO, MSO or SE... but for some reason can get here...

Mark Szymanski

Weird.

David

try closing your browser, using ccleaner (clearing temp files), then retrying.

DMA57361

@David done all that, reset router as well

most of the internet is working fine as well, only found the SE sites problematic

hmmm, doesn't work in other browsers either >(

TomWij

@DMA57361: Can you reach stackexchange.com?

DMA57361

TomWij

Jan 20, 2011 18:18

@DMA57361: Have you tried pinging the sites?

ping superuser.com should give 64.34.119.12.

DMA57361

no... was messing with dns h/o

@TomWij yup, matching result here

TomWij

What does a tracert or pathping (Windows only, more analysis) with the parameter superuser.com reveal?

DMA57361

it routes "successfully" to stackover.com [64.34.119.12]

(althought one step in the chain is a set of 3 timeouts)

TomWij

Hmm, so no DNS resolving problems, it didn't show dropped packets either?

KronoS

@DMA57361 @TomWij funny... I'm writing up a blog entry on DNS issues

DMA57361

Jan 20, 2011 18:22

nothing dropped except the line that failed entirely

switching to google's DNS and clearing everything doesn't seem to have helped either

TomWij

@DMA57361: Do you have Google Chrome?

DMA57361

I have it installed, yes, but I've not tried it yet

(for this problem, I mean)

TomWij

Try it, if it doesn't work then visit chrome://net-internals/ and try:

- Check if the proxy tab lists the right settings, these should be the ones taken from Internet Explorer.

- See if the event tab lists any errors, and see what it lists when trying to resolve superuser.com, for me it gives:

DMA57361

there's no proxy settings, which is correct

TomWij

(P) t=1295547738381 [st=0] +HOST_RESOLVER_IMPL_JOB  [dt=8]
                        --> host = "superuser.com"
                        --> source_dependency = {"id":42493,"type":7}
(P) t=1295547738389 [st=8] -HOST_RESOLVER_IMPL_JOB
                        --> address_list = ["64.34.119.12:80"]

- See if the DNS tab lists a superuser.com entry, for me it gives:

superuser.com	ADDRESS_FAMILY_UNSPECIFIED	64.34.119.12:80

DMA57361

Jan 20, 2011 18:27

superuser.com UNSPECIFIED 64.34.119.12 33168

TomWij

@DMA57361: And if all looks fine, the tests tab should allow you to type in superuser.com and show you a lot of details.

DMA57361

erm, this page isn't tabbed ? ... I may have an old version

TomWij

I only get errors where it says "Use Firefox's proxy settings", but that's because I don't have Firefox. Nice to see it's smart enough to probe Firefox when Internet Explorer is broken... :-D

Isn't there a tests tab?

DMA57361

on chrome://net-internals/ there's no tabs at all - just lots of sections above one-another, and I can't see "tests"

TomWij

@DMA57361: 10.0.634.0 dev here, but well, some statistics aren't fully implemented but they should be sufficient to troubleshooting where the problem lies.

DMA57361

Jan 20, 2011 18:30

lol

5.0.375.127

let me try updating :)

TomWij

@DMA57361 Seems like an old version, isn't there a textbox at the bottom which allows you to test?

> Blog: Chrome on stable channel has been updated to 8.0.552.237 for all platforms.

DMA57361

chrome isn't my standard browser

TomWij

Yeah, probably not a bad idea.

Yeah, I just don't know how to troubleshoot in other browsers, but I guess that looking for network diagnostics there might give similar pages.

DMA57361

much better...let's have a look

tabs! ah ha :D

testing now

FAIL
Fetch http://superuser.com/ Don't use any proxy
-101
41960

second one is also taking ages...so doesn't bode well

do you know how many tests it tries?

TomWij

Strange, you can ping to it, so you can reach the machine and packets aren't dropped.

To me that would say that something is filtering your network traffic.

Have you tried disabling firewalls?

DMA57361

Jan 20, 2011 18:39

only have the Windows one on

TomWij

@DMA57361: Try disabling it just to be sure that the settings aren't messed up. Although...

DMA57361

anywhere have a list of the error numbers these tests return?

all I'm getting is -101

TomWij

It might be unlikely that something is specifically blocking superuser.com.

DMA57361

na, not change

@TomWij and stackexchange.com and stackoverflow.com but not chat.SE.com...

TomWij

ERROR: Error 101 (net::ERR_CONNECTION_RESET): Unknown Error

DMA57361

Jan 20, 2011 18:42

is chat on a different IP range?

@TomWij ah...

TomWij

By googling "google chrome 101".

DMA57361

well all tests complete, all FAIL after ~41s

TomWij

Connection reset would seem like a firmware action, either by ISP or by your Windows Firewall.

DMA57361

@TomWij ah, I was being too specific it seems

TomWij

@DMA57361: Yeah, likely to be timeouts.

DMA57361

Jan 20, 2011 18:43

oo, I can get to meta.SE as well

TomWij

Chat is 69.59.196.211 while SU is 64.34.119.12 while Meta.SE is 64.34.80.165.

So yeah, looks like different ranges.

DMA57361

well...maybe I'll just have to do something else this evening

TomWij

@DMA57361: If disabling anti-virus, firewall and cleaning temp data doesn't resolve anything; then yes, it might be your ISP...

Those are the suggestions I can find from Google Employees.

Cleaning temp data won't help as you are just getting the right IP.

Windows Firewall is unlikely as you probably haven't blocked the site or IP specifically.

So, an update or setting change to your anti-virus software (that has web filtering) could probably be the issue; if it isn't the ISP.

DMA57361

hadn't though of AV, but it didn't help

TomWij

But yeah, troubleshooting has to end somewhere. I wouldn't feel like calling the ISP either, unless the issue remains for a long time.

DMA57361

Jan 20, 2011 18:51

hmmm, oh well

thank's for your help

TomWij

Leaned pathping while I had problem some weeks ago.

I had a perfect connection with people from The Netherlands while gaming, but there was weird lag when gaming with someone from America.

Furthermore, scalable sites like Google just work fine, but Stack Exchange didn't work for me either.

But, it was just an issue that night and it didn't come back later...

Guess some major switch was having issues.

DMA57361

odd
