Trouble with the BT Wholesale checker as linked to above is that it will eventually block an IP address if used too often.
Yes, I've already thought of this, but assumed it would block you fairly quickly. Would you be willing to share the code? One solution may be to do a daily call of the max limit from the five or so websites that let do these queries, and do that from multiple IP addresses... over a year I could get quite a granular data set, and then I could interpolate from these for the whole of the UK. Thanks for the data you posted on your local cabinet locations - I had found this in a previous thread, and would be willing to share any data I collect.
the UK's digital infrastructure is far greater than just street cabinets, you've Virgin Media, Hyperoptic, Gigaclear, B4RN, and many others before you even get onto Dark Fibre suppliers. Shouldn't you include these?
Yes, I totally agree, I'm just working on the fixed access component right now, but the aim is to cut across fixed (access and core), mobile (3G, 4G, 5G), wireless and satellite. SamKnows has some data on the Virgin Media footprint which I was going to use, but I would very much welcome any suggestion on where Project Lightening rollout may be taking place as I don't know how to tackle that yet.
As for Hyperoptic, Gigaclear, B4RN etc. I may have to result to taking national market share and disaggregate this based on network presence. In the absence of any better data, this may be the best available option, unless there are any further suggestions?
