Google have recently released an update to their mobile chrome browser that many android and some apple devices use. Within the new release is a new feature called Google's Bandwidth management system which tries to reduce your data usage and bandwidth by compressing the data.
However this also enables the connection to run via Google's SPDY proxy server meaning that websites may identify the connection from a non-UK based IP address.
At the moment if you have the Google's Bandwidth management system enabled on a mobile Chrome browser and visit the BBC website it loads the international BBC website, as well as not allowing you to play content from BBC iPlayer due to it thinking your not in the UK.
(We may start getting threads saying that they can't visit websites or watch catch-up tv services from their mobile devices which use Google Chrome due to this new feature)
At the moment I don't think any of BT Retail's websites/services will be effected by this though maybe something to look out for. (Though not sure how it will effect BT Retail's new webfilter.)
It looks like that any website with SSL/HTTPS encryption bypasses Google's SPDY service and therefore won't be effected by the (presumably) US based IP address used.
I'm also not sure if Google or browser/software companies will start to adopt this level of security (like the SPDY proxy server) or bandwidth management service to their desktop software versions.
@Keith, You may notice this on your website. I have tried to access your website with the new Google Bandwidth management service enabled, though your website fails to load. It loads fine when the new Google feature is disabled. (tried several times around 21:24)
This sounds similar to the Opera Mini Browser, which fetches all pages via a proxy which compresses the pages, befor passing them on your phone.
This reduces data usage on a 3G connection, but is of no benefit if you are on a wifi connection.
Did you try this on a 3G connection, or was it on Wifi?
The connection is via Wifi and not via the mobile network connection.
I don't think Google have added a feature that would temp turn the new Bandwidth managment and SPDY services off when connected via Wifi instead of a mobile connection.
Though you can manually turn it off by yourself in the device and chrome settings.
You are right, its something to watch for. When you visited my website, did you get the message about not connecting from BT. This is in fact as simple redirection of the normal 403 (forbidden) message.
It seemed to take ages to load, and then just appeared with a blank screen. (just tried again around 22:05)
At the moment with the Google bandwidth (and SPDY) enabled some websites such as the BBC display you limited content and prevent you from watching the iPlayer service.
Though not sure if it will effect any of BT Retail's websites/sevices or the new BT Retail web filter
Edit: With the Google bandwidth (and SPDY) enabled my IP Address is in the subnet range of 126.96.36.199 - 188.8.131.52 which belongs to Google.
