Search results display old version and new version according to IP?!

Can anyone shed some light on the following issue:

When I search locally for my website I see an old version of my website.

When I do the exact same search through a proxy like hidemyass.com I see my new and updated version as it should be.

Its quite annoying.

Thanks.

Your isp seems to have cached the old version of your website. It should be updated within the next couple of days. If not I suggest you give them a call and ask what's going on.

Indeed, it has been around 2 days now. I even switched to OpenDNS to see if there was any difference but there was none. I'll have to wait I guess.
