Context: I teach at Princeton and used to work at the FCC.
Several comments suggest systematically comparing FCC data to what ISP websites say about availability. My research group did this! Here's the paper:
https://dl.acm.org/doi/10.1145/3419394.3423652 https://dl.acm.org/doi/10.1145/3419394.3423652
And here's a followup project by investigative journalists at The Markup:

That article is pretty bad. It doesn't once mention DSL or that technology's inherent technical limitations that can result in widely variable speeds (IIRC, your bandwidth is determined by the length of the wire between your house and the central telephone office). Then it spends a lot of time talking about race, which is likely creating a misleading impression that lends itself to outrage.
- tguvot 4y agoDSL bandwidth is determined by the length of the wire between DSL modem and DSLAM which can be in the cabinet on the curb (and I believe it usually is). Also it depends on what version of DSL standard we are talking. I personally started with adsl2 which was 12/3, upgraded eventually to VDSL2 which did 150/10 and latest standard is G.Fast which can give 1 Gbit/s aggregate uplink and downlink at 100m
- Retric 4y agoThe odds of having a cable under 100m to a DSLAM basically rounds to 0. At an highly optimistic 1 mile you’re already down to 20Mbps and most people are significantly further than that. Remember it’s the physical distance of the cable between the actual devices that matters and that’s not straight.
- tguvot 4y agodepends on location. and on greed of the telco. i used to live within 100m of dslam. in cities with dense construction/etc it's achievable. also, with g.fast it's 1000 aggregated at 100m. for longer distances numbers are 200 m 600mbit, 300m-300mbit, 500m - 100mbit. numbers are not too bad even for suburb. For comparison, high speed mm wave 5g needs to be deployed any 100-200m in order to get proper speed/penetration. admittedly, even g.gast it's not as good/scalable as DOCSIS or Fiber, but it could be used and deployed "back in a day" as perfectly good solution. and even today it's not that bad for majority of population, if properly deployed as anecdote , i saw like 20 years ago privately deployed/managed DSL systems in kibbuz. wonder what they have now
- Retric 4y agoAgain you can’t directly compare distances between 5G and DSL because the wire isn’t taking the shortest path through 3D space between teleco equipment and your modem. Also a single 600-700MHz 5G tower can cover hundreds of square miles with 5G service with up to 250 megabits per second. 2.5-3.5GHz can still hit several miles with up to 900 megabits per second, and 24-39GHz towers can cover a mile radius at up to 3Gbps. Real world performance depends on many many factors, but DSL performance can be similarly degraded from it’s theoretical maximum.
- tguvot 4y agoi compared with mm wave 5g because it requires same density of deployment as DSLAMs for proper performance, if not higher. > Real world performance depends on many many factors, like how many UEs are sharing spectrum. Which is usually a lot > but DSL performance can be similarly degraded from it’s theoretical maximum. totally.
- FireBeyond 4y agoOn multiple areas, AT&T (I believe) successfully petitioned the FCC to not count a bunch of low end DSL and similar services, on the basis that they were "obsolete" and lowering averages. To be clear, they were still actively selling those services, and in some cases, it was the only option, but they just didn't want them to count.
- runnerup 4y ago> Here's the paper: It's super-paywalled. Can you upload a copy of it somewhere?
- mistrial9 4y agothat video presentation is heroic! what a riot to see the numbers sliced that way; and you are clearly cautios in the estimations. well played
- philsnow 4y agoI'd like to read the paper but not $15 want to read it. Apparently ACM wants to charge $5 or $10 for this one article even if I had a membership. Is this one of those situations I hear about where researchers would be super happy to provide copies of papers that ACM etc keep behind paywalls, if you just ask?
- zxexz 4y agoThey most likely would send you a copy, I have a 100% success rate with that. Though I should also mention that paper is present on scihub at this very moment.
- viraptor 4y agoThere's a helpful raven at the hub of science for that ; ) https://sci-hub.ru/https://doi.org/10.1145/3419394.3423652 https://sci-hub.ru/https://doi.org/10.1145/3419394.3423652
- TomSwirly 4y agoSo in other words, all the telecoms are systematically lying to the FCC in order to steal money from taxpayers, but there is no actual enforcement nor penalties for doing so, so they continue to do this with impunity. (I remember when Clinton gave away a huge giveaway to the telecoms so they would provide fibre everywhere, and then they did fuck all and just laughed.) In a just society, they would quickly be presented with a estimated bill for the largest amount that they could possibly have stolen - I'm sorry, let me repeat this word "stolen" - from the US taxpayer, PLUS massive penalties, and then they would be required to prove how much they actually stole if they wanted to reduce the cost. Plus complete discovery of all their records should be required, with a view toward criminal prosecution of their executives. As it is, they have absolutely no reason not to cheat, lie and defraud if they think they can make money at it.
