    Default Optus re-compression of images over 3G

    Optus recompresses images downloaded over 3G (recently got much worse in the past 4 or 5 months). This isn't noticeable on my iPhone of course but it is extremely noticeable when I'm browsing the web with it tethered to my MacBook. It's going to suck if they apply the same policy to iPad traffic.

    I'm assuming most telcos will do the same thing to some degree but wanted to hear about other people's experiences ?

    Would suck if you were paying for unlimited access.

    Not so bad if your paying by the MB.

    Certainly something to be mindful of if you're considering Optus for an iPad plan.

    is there an offical page on the Optus web site that explains the level of compression in more detail? do they offer a way to turn this off?

    switch to Telstra and breathe

    I'm gonna go with Telstra for my iPad.
    To buy or not to buy? That is the problem.

    Telstra don't do it, and I didn't notice it on Vodafone mobile broadband either.

    Here you go, you motivated me to blog about the issue: Josh's ramblings, Optus 3G image recompression

    I'll be chasing this up. When I spoke on the phone, they said it only affected people 'with iPhones using tethering'. I do occasionally use tethering, but this is affecting me even just browsing on the phone. Unacceptable.

    Jesus, this is the same crappy technology they used to 'speed up' 56k connections years ago. Has Optus' network really gotten so bad they have to resort to this?

    T-Mobile do it as well, however their software has an option to turn it off. I found it breaks a lot of applications, and just looks down right crummy.

    Have a little look at the source of your pages, if I remember correctly the images will be rewritten to come from an internal ip address with the full path appended to it.

    Josh, that is amazing - I can't believe Optus would do that.... then again, yes I can - It is Optus after all.

    Can they actually do this? Is it breaching the contract I signed in any way?

    Yeah, I posted on Whirlpool about this in April (Optus image compression on 3G/GPRS? - Optus / Virgin - Mobile carriers - Whirlpool Forums), but got no response from any of the Optus reps that post there.

    This annoys me to no end because it really degrades the experience of using the web on my phone.

    The quotes from Optus in the ZDNet article about it being innovative and beneficial to customers are a load of crap. This reduces their network load, pure and simple - and they introduced it at a time when their network was severely straining under the loads it was carrying. Their motivations for introducing it are in my mind quite clear.

    I honestly don't mind if they offer it as a "Web Acceleration" feature, because I think some would choose quicker load times over quality, but they could at least give us the option to turn it off.
