Reader Jonathan watches a lot of Netflix since he cut the cable TV cord, and since he used more than 270gb of data, Comcast notified him that he was nearing the limit of his "monthly data usage allowance." Jonathan wondered how Comcast was able to send this message, and it turns out that they injected the message code into webpages he was viewing.
The notice reads: "You have reached 90% of your monthly data usage allowance. Please sign in for more information and to remove this alert."
You can use up to 2.3 gigabytes of data per hour if you're watching streaming in HD resolution, according to the Netflix help system.
Has anyone else seen this warning from Comcast?
