Technology has continued to progress but I think many cable providers are capping at around 100 mbps. I could be wrong.
I think most are offering as high as 1-2Gbps (asymmetrical) with cable. That’s what Comcast is offering in our area. With 100Mbps CenturyLink DSL being the only alternative.
Comcast has done some wizardry to finally allow decent upload speeds as of late. For years I’ve had 900Mbps down and 15Mbps up but with whatever upgrade they’ve done, I’m now at 900/200 which is decent enough. I honestly don’t even need all this download bandwidth and would be happy with 500/500 but most people aren’t running media servers and hundreds of torrents so they don’t dedicate much to upload bandwidth.
