They get above 20Mb on their Exchange Only ADSL line and think it should be some special priority to be upgraded.
Why an EO line "feet from the exchange" should have some kind of priority over a line connected to an FTTC cabinet 2 miles away is beyond
This petition is of course pointless as it is not currently a political issue (and even if it was, petition written like that would not get you anywhere) but I wonder about the origins of the notion that EO lines are generally super fast on ADSL standards.
There are of course many of those (near exchanges) but at least in London it appears to be 80's and early 90's thing to cable everything to the exchange, no matter how far away. Some of these areas were done using aluminium, not copper. East London has plenty of EO areas where average speed is 2-3mbps. FTTB providers have generally done most blocks of flats but those in houses do not have anything better in sight - 4G USO service with a data cap will not be of much help to an urban streamer or online gamer.
Despite spamming and a badly written petition EO lines are a pain. They are the most expensive to upgrade and it seems that they are just being ignored. Quite a lot of investment goes now to upgrading FTTC areas to FTTP or FTTC to G.Fast as the current Openreach business model just does not have an incentive to do anything to the areas expensive to upgrade. There is always a new technology or something else that directs the investment to non-EO areas.
For example in my inner London constituency full fibre goes forward in amazing leaps according to Thinkbroadband statistics. Every month shows an increase in full fibre footprint - but the percentage of non-USO compliant lines remains strong and stable at 7.6%.
Not sure what can be done if anything but the problem is real.
