Given the thinkbroadband/pointtopic datasets regarding network topology laydown, I'm wondering if there is any opensource or paid-for data that provides an overview of network capacity, quality of service for the various ISPs?
What about visibility of ISPs serving buildings?
wouldnt samknows/vm link kinda work with this? (not public information though, but surely the information is there?) o.0 I used to have a samknows box years ago, but it seems built into hubs.There isn't, no. The capacity is only known to the ISPs, the quality of service, I presume you mean what customers are getting on various ISPs, is basically the same as the speeds customers are able to achieve.
The database you want doesn't exist and, in the case of network capacity, can't. Quality of service would need automated testing and reporting to public servers which doesn't happen right now.
you can use https://bidb.uk/ to search a postcode and see what covers it.What about visibility of ISPs serving buildings?
