Here are some links to the instructions (current as of March 2015): \n\n Netflix\n YouTube\n HBO GO: Manual video settings are not available. HBO GO will automatically adjust video quality based on the strength of your network connection.\n Amazon Prime: When watching directly in the browser, there is an "HD" indicator as one of the auto-hiding controls. It says "Watch in HD" and can be set to "Off." For downloads, select the SD version.\n Hulu: Watch a lower quality in the browser, or look for directions about how to "lower the video quality during playback" on this Hulu Help Center page for other streaming devices (scroll down for a full list of devices).\n See how to Reduce NUBB Usage at: http://www.it.cornell.edu/services/nubb/howto/reduce-usage.cfm\n\nReduce video streaming usage\n\nYou can reduce usage by setting up Netflix or other services for lower or standard definition (SD), which uses far less bandwidth and looks just as good on most devices.

After an uptick in calls from students, to the IT Service Desk, regarding higher NUBB charges than usual, CIT ran an analysis on 10 heavy users to verify that NUBB rollups were working as expected.\n\nThe results were very consistent. The bulk of the traffic is video. It was NetFlix, Google, Amazon, Akamai, Facebook, then a few less-used services including EdgeCast, Comcast, Justin TV, and NForce Entertainment.\n\nFurther investigation showed that higher-bandwidth HD video is probably the culprit. Over the last year, HD video feeds have increased from 1.5G/hr to 3G/hr or 7G/hr for Ultra HD video. Fortunately, it is possible to reduce usage by setting up video services (Netflix, etc.) for lower definition. Details about how to reduce video streaming usage for a few popular services have been posted at the NUBB service site: http://www.it.cornell.edu/services/nubb/\n\nIn addition, CIT is discussing new communications procedures and opportunities to increase student awareness of this change and minimize unwanted NUBB billing.\n\nNUBB is a billing system and application used to administer and recover the cost of university Internet (WAN) usage. It is designed to ensure that network costs are covered, including anticipated upgrades, and that the costs are distributed in a way that reflects usage patterns.\n After an uptick in calls from students, to the IT Service Desk, regarding higher NUBB charges than usual, CIT ran an analysis on 10 heavy users to verify that NUBB rollups were working as expected.\n\nThe results were very consistent.
