Re: Can not visit some website from china

Hey @OliverXu, have we asked you to run a traceroute? That way we can establish whether it's a DNS/routing issue. Have you also tried several different web browsers? The trace route should give us an idea of where the path is broken. I'd suggest running the traceroute and PMing us with a screen shot of the result. If you could also include your fault ticket number, that'd be great. We can send it through to the team looking after your case.

 

You could also try a VPN or an alternative DNS server such as Google DNS or Open DNS

Re: Can not visit some website from china

Hi @Dan_C, thanks for the following-up. I did. I ran traceroute and ping on Optus cable network and non-optus (my mobilephone 4G) network. I sent the screenshot to tracert@optus.com.au. Reference Number: 1754 4651. 

 

I also tried on different browsers and different platform. It came with the same result.

 

You mentioned to try an alternative DNS server. Could yo shed me some light on how to set it up?

 

Thanks.

VPN resolve the issue.  I've tried my company VPN, which moved all traffic to telstra NBN.  DNS has not effect, I'm using Google DNS.

Re: Can not visit some website from china

I was asked to do a traceroute as well and send it over, but I'm at work and I can't do it until I get home.

The issue is not just qq.com or web.wechat.com, but also it is affecting the wechat application when receiving photos.

 

How can you change the DNS? the optus provided router does not give you that option. It's set by optus.

so where are you changing the DNS from?

Re: Can not visit some website from china

Changing the DNS through the PC is not the solution, because what do you do with the wireless devices?

Optus does not allow you to change the DNS settings in the sagem fast modem. so that is not a fix.

Re: Can not visit some website from china

@Dan_Cwhere/who would you like us to send the PMs about this to?

 

The optus provided router does not allow you to change the DNS unlike other routers,

so the alternative is to change it in windows network properties, but that will not work for wireless devices.

 

The issue is not just websites, when using the wechat application, I can't receive photos, someone tries to send me a photo, the apps sees it, it just won't download it.

Optus NBN cable users are not affected, only Optus Cable users.

Re: Can not visit some website from china

Hi Guys,

 

This is appears to have been fixed by Optus. I just tested it and everything is back to normal. I also got confirmation from the optus rep that this was resolved by the back end team.
