Wow, lots of nasty replies there! I didn't say that I personally am hosting the site - the company I work for USED to do hosting - I'm just trying to figure out a problem. My time zone and other commitments prevented me from checking back until now. And please - I'm not trying to spam any site.

Thanks for the genuine replies. I've refreshed the page in IE, Firefox, Opera - and they're all showing the old logo. We still host our own website (on the same server as the one giving the problem - we only have one webserver, btw), and I maintain the site and have NEVER come across this problem - on our website I update a page, and bingo, the changes are live immediately when I refresh the page in the browser.

I've restarted IIS and it made no difference. I pinged the domain name and it also shows the same IP address - one in our range. I also did an NSlookup on it and it shows the same IP address.

I downloaded VisualRoute to do a traceroute, and it showed 6 hops, but also said that the host could not be reached "it does not respond to VisualRoute's diagnostic packets. Hops after hop 4 could not be identified - this is usually indicative of a firewall at that point". It did show a header saying 'Report for <website address> [IP Address]' and sure enough it's the same IP address as all the other tests.

As far as I knew we had stopped hosting this company's website some time back...
