I cannot access some international sites this morning.    

I am on the telecom adventurer plan.   I've rebooted the adsl modem, and the pc too. 

Some sites not working...
www.ibm.com , www.cnn.com,www.microsoft.com 

Some are working ok, eg, www.apple.com is just fine. 

All domestic sites are OK. 

Just wondering if anyone else has issues?

I just noticed, www.microsoft.com has started working ok, but the others still down.

Try clearing your DNS cache (Start > run cmd > type ipconfig /flushdns) and make sure your DNS servers are set to Telecom's.

I'm having the same problem accessing International sites. It's not just you.
I can't even get gmail.

I tried connecting through my vodafone 3g, and that works just fine. So, it is just telecom.

Same problem here.
On the Telecom service status page they currently have this message up:

Some customers may be experiencing problems surfing websites and checking emails. Our technicians are currently working on this problem. At this stage our representatives are unable to provide any additional information. We apologise for any inconvenience.

Thanks Brimstone. Looks like that message has just appeared; it wasn't there 15 mins ago.

yup i have the same problem.

you can check the status at: http://www.telecom.co.nz/help/servicealerts

it's odd because its only certain sites. Luckily the wife can still stream Glee on her laptop so I should still have a nice relaxing Sunday ;)

At least I have my trusty 14kbps Dial-up today... Can get onto all international sites after about 5 mins of waiting! Cant wait for development here.... Hopefully it's coming soon!

Can't check Yahoo!Xtra email either. It must be hosted overseas.

I'm not having any problems accessing any of the above sites. So it doesn't appear to be a general problem.

Currently I'm on a 219 IP range and connected through the cache farm, so that might be making a difference.

Just tried yahoomail.com as well and that is working, so obviously the cache farm won't be impacting this.

Hi,

I am (as would be expected) running through the cache farm and have no issue to the above sites.

I do have an issue with gmail and wave but that is something weird i have been tracking on my setup for a few weeks as its an HTTPS connection to www.google.com that times out and we dont cache HTTPS.

Are there more examples of sites that don't work?

Now for the standard questions well all love to loath:
* Have you reset your modem
* Are you using Telecom DNS servers handed out automagically
* Have you cleared your local DNS cache as noted above
* Have you cleared your browser cache
* Have you raised a case with support
* Are you using some sort of web filtering service from a provider

What is always useful to someone like me is a comparison of what IP you are seeing as the resolved one for the site you are going to with other people that are/arent having the same issue.

Traceroute is good as well to tell you path, its a bit of fibber about latency though.
And if you can, tcptraceroute is nice as well, sometimes it will give you information you missed with a standard traceroute.

And of course MTR or WinMTR is good for spotting issues as well.

That was a bit of a ramble but if you post URL's that are impacted i can test from my side as well.

Regards

Paul

Never having used gmail and never having had problems accessing other secure sites I can't be sure, but I have noticed that one gateway I was assigned to was running a smaller MTU. Perhaps gmail is more susceptible to fragmentation and a setting a lower MTU on your router may resolve your problem?

Thanks for the pointer, its been a long while since i thought about MTU... I know i had to change it for a lab i setup recently.
Ill try that out.

Thanks
