Knology's Sunflower-era web page hasn't been updated with the new plan information, but in return for that extra three bucks a month, here's what you'll receive:
Bronze: Knology's low-end service retains its DSL-like 3 megabit download speed, but gets a nice boost in upload speed to 1 megabit (up for 256 kilobits). The bandwidth cap for the Bronze service gets a slight bump for 3 gigs a month to 5 GB, which is still ridiculously low. At $22.95 a month (assuming you already have cable TV), Bronze is still a very poor deal, as even a single system update or movie download would blow through the puny bandwidth cap and have you paying overage charges.
Silver: Knology's mid-range service gets a solid speed boost, going from 10 to 18 megabits in download speed and 1 to 2 megabits in upload. The bandwidth cap remains 50 GB, for a monthly price of $37.95 (if you have cable). The bandwidth cap is still too stingy, but the speeds are very solid for a mid-range option. For most people, Silver is the definite sweet spot and probably the best value as long as you stay under the cap.
Gold: Knology's premium service for serious internet users retains its old 50 megabit download speeds, but gets a major upgrade from 1 to 5 megabits for upload, finally making Knology useful for common tasks like online backups and video uploading. The 5 megabit speeds might even be understating things, as anecdotally, some Knology Gold users have seen speeds in the 6 or 7 megabit range at least in shorts bursts uploading. At $62.95 (with cable), Gold is pricey, and sadly, Knology has not upped the barely adequate 250 GB monthly bandwidth cap. For a premium service, it would be nice if Knology offered the 500 GB caps that many other providers offer for their highest-end service.
Palladium: Knology's cap-less Palladium server, now $47.95 a month (with cable), still offers download speeds of between 2 and 25 megabits, and upload speeds up to 1 megabit, unchanged from before (other then the higher price). Palladium may be a good value for those who move a lot of data but do not care about speed - perhaps folks with nailed-up VPN connections, or large continuous online backups.
The improved upload speeds are a good value for only $3.00 more a month, and it is nice to see Knology offering speeds that are at least mainstream, but here's hoping WoW continues to improve things - DOCSIS3 is capable of much faster speeds, and many providers off 10 megabit upload and much higher caps. Still, Knology has definitely thrown a gauntlet towards U-Verse, who offers 24/3 on their fastest data tier at roughly the same price (albeit without currently enforcing any bandwidth caps).
