  • There are now at least new plan names Connect More (200), Fast (400), Superfast (800), Gigabit (1000), Gigabit Extra (1200). These can be found here: https://www.xfinity.com/digital/offers/plan-builder Address info required. I used Boston MA. This page also shows Internet Essential\ACP 50 and 100 Mbps plans which require one to meet certain requirements: https://www.xfinity.com/learn/internet-service

  • This page hasn't been updated and is no longer accurate. For example, Extreme 400/20 is not even on the list.

    2021-04-25 21:01:29 (INTREPID See Profile)

  • Currently, I believe the D3.0 speed tiers look like this: Central Division Performance: 100/5 Blast!: 200/10 Extreme: 300/20 Extreme Pro: 600/20 Northeast & West Divisions Performance Starter: 25/3 Performance: 100/5 Performance Pro: 200/5 Blast!: 300/10 Extreme: 600/15

  • In the SF Bay Area the Extreme Pro 600/15 tier is live and functioning well (my grandpa has this tier).

    2020-05-09 06:31:15 (NeilPeart See Profile)

  • My grandpa is on a 600/15 service in the Santa Clara County part of California (Bay Area). I don't see this tier listed here. Thank you.

  • I didn't keep track of upload speeds, sorry, but in the greater Salt Lake City area as of today these are the packages currently offered by Comcast - with their regular non contract pricing for Internet service only: PERFORMANCE STARTER PLUS; 25 Mbps; $50 PERFORMANCE SELECT; 100 Mbps; $55 PERFORMANCE PRO PLUS; 200 Mbps; $70 BLAST! PRO; 300 Mbps; $80 EXTREME PRO PLUS; 600 Mbps; $90 GIGABIT; 1000 Mbps; $100 GIGABIT PRO; 2000 Mbps; $299.95

    2020-03-09 17:59:39 (Gork See Profile)

  • What are the actual Provisioned Speeds? https://www.dslreports.com/faq/15643 This page needs to be updated. For example, Comcast now offers Extreme Pro 600/20 (residential) which is not reflected in your chart. Thanks.

    2019-11-28 00:32:11 (INTREPID See Profile)

  • I have been told the same as wtbman. Oregon service address; Performance Plus 75 Mbps/5 Mbps, Performance Pro 175 Mbps/5 Mbps, Blast! Pro 275 Mbps/10 Mbps, Extreme Pro 500 Mbps/15 Mbps, No change to gigabit.

  • You may need to update this site with new information next week. I've heard from two Comcast customer service reps speeds are increasing across the board (at least in Utah) next week. Here are the speeds they provided to me: Performance Plus 75 Mbps/5 Mbps Performance Pro 175 Mbps/5 Mbps Blast! Pro 275 Mbps/10 Mbps Extreme Pro 500 Mbps/15 Mbps No change to gigabit.

  • Thank you! Excellent information! Could you please amend the "Advertised Speeds" column header with "(Down/Up)", and add a column header for "Measured Speeds (Down/Up)"?

    2018-01-16 11:53:38

  • Here's one more thank you for great (and necessary) information.

    2017-11-04 09:10:47

  • Thank you very much for your work! My speed (Preformance Pro 25) reflects what you listed.

    2017-10-26 22:43:43

  • Good job on the FAQ. Those upload rates for xfinity are horrid.

    2017-10-07 00:23:50

  • Great that someone provides this. People should know what they should be getting.

    2017-02-11 09:13:33

  • Great Info! With my upgraded Netgear C7000 Modem/Router I'm hitting the cap of the Xfinity Blast (NE) / Blast Pro [200] @ 242 Mbps / 12.1 Mbps.

    2017-01-16 13:08:34

  • Thanks for the VERY thorough break down.

    2017-01-04 21:23:09

  • Excellent job. THANK YOU. Comcast does indeed try to keep it secret. Next of course is ensuring they provide the service we pay for in a monopoly cable provided situation and the recourses we have. FCC is a waste of time. Thank you once more for tabulating this valuable info.

    2016-12-21 21:36:16

  • Thank you for posting this. I'm certain that the provider intentionally scrambles the specs so consumers can't research what they are paying for.

    2016-10-31 22:07:48

  • spent forever not finding this on Comcast site - many thanks

    2016-10-31 21:37:33

  • I really appreciate this info! So helpful <3

    2016-09-28 16:07:55

  • This is awesome and helped so much. Nice job!

    2016-09-08 14:50:35

  • Yes, thank you!! The silly comcast rep didn't know and gave me some wrong numbers!!

    2016-07-17 12:53:08

  • nice and simple. thank you for taking the time putting this together!

    2016-05-10 02:31:24

  • Thank you for taking the time to produce this excellent, simple and well-designed source of info!

    2016-04-28 08:28:03

  • Thank you for a superb level of information. Wish the upload speeds were at least more inline with downloads. Perhaps that will happen someday. It's clear why they hide it.

    2016-04-10 17:33:00

  • This helped me negotiate a price with Comcast this afternoon. They didn't offer me the Blast 75 package, and I ended up being escalated to a Tier 2 rep to get what I wanted. Thanks!!!

    2016-03-11 20:39:55

  • Fantastic--Thank You! It's impossible to find this information on Comcast's convoluted site. Especially the upload speeds.

    2016-02-17 02:58:16

  • Awesome data!!! Comcast is as transparent as Congress now...

    2016-01-26 03:43:18

  • I have bookedmarked this excellent resource and many thanks for posting.

    2016-01-15 23:16:17

  • Outstanding! Thanks! This information is practically impossible to obtain from Comcast/Xfinity.

    2016-01-02 11:54:17

  • Thank you! Thank you! Thank you! I've been struggling finding this for hours!

    2015-12-20 08:48:54

  • Thank you for this. Comcast makes it extremely difficult to find this information on their website. THANKS!

    2015-11-27 12:36:22

  • Great job and thank you for this info! Adding the average cost per tier would also be very helpful!

    2015-11-23 09:14:02

  • Great layout. It's nearly impossible to find this simple information from the Comcast website itself. Adding the regular monthly cost per plan could help make it even more useful.

    2015-10-14 18:11:22

  • ty very much for this

    2015-10-02 00:43:25

  • A big thank you to BroadbandReports' volunteers for taking the time to create this content for us all to access. It is clear, organized, accurate, and most importantly, useful!

    2015-05-26 01:41:58

    2015-03-29 17:27:40 (Sunny See Profile)
