I've been without a proper broadband line for a few weeks, due to a wait with ISP for a connection at my new office.
I've been reluctantly using Mobile Broadband for this period and have noticed a worrying trend - sites of all shapes and sizes are breaking due a script my ISP has implemented to compress all js/css/html and render images at about 90% compression.
I'd hoped the script was located on the dongle itself, so disabled the software and connected through prefs, no luck. The script is served by the ISP directly.
Site's that I've noticed problems include some of the largest social media, shopping and bookmarking services, amongst others. So would indicate it's not just affecting jQuery (as I first thought) but also Bootstrap and custom js.
Anyone else notice this? Could be a minefield if a client is using Mobile BB - not to mention their customers... useful to know, but #*$! hell, why should we have to accommodate this sloppy code with no option to disable or bypass?
(note mobile browsing natively, using HTTPS or via mobile tethering doesn't seem to use the same archaic methods).
