Hello all...could someone on a PlusNet broadband connection please try to access http://www.sainsburys.co.uk and post whether it's working for you?

Not working here (but I am on John Lewis BB)

http://downforeveryoneorjustme.com/www.sainsburys.co.uk has no problem.

Can you change DNS, or are you tied to Plusnet DNS?

All ssems to be working here. Is it a dns issue?

Using Plusnet BB and website works for me.

You're right, it does look like a DNS issue...what are you getting from a lookup on www.sainsburys.co.uk?

Working here (using OpenDNS).

Hmmm ... it looks more like a routing issue. Traceroute takes me into the BT network -- and stops. I think a DNS issue would stop immediately as unable to resolve the IP address.

I'm not on Plusnet, but a very odd tracert and ping response.

I have no problem accessing the Sainsbury's website. Yet I get the following at a command prompt.

Thanks Bob...working for me now. PlusNet were serving a 'null' response to DNS queries for www.sainsburys.co.uk for a while, now seems to be OK.

Sainsbury's have never allowed ping traffic so it always gets blackholed at some point in the journey,

I can access the link in your message without a problem.

Opens in three seconds for me, on Plusnet in N. Ireland. Used it yesterday pm (Tuesday) without problems.

I have just finished a phone conversation with Plusnet. Unable to connect during the debug session, but all ok now. Concidence?
