Unknown cause of High Data usage
On 4/18/2025 my data at 9amCST was 633gb and by 7pm I got email saying I've used 75% of data, I chatted with tech support about it and they said it was error in system and was being worked on would be fixed within hour and real data usage would be back, that never happened I then talked on phone about same thing and the technician said they were seeing the high usage of data coming in and I verified with him that there were no devices connected to the modem router. I was on phone with him for 53mins and he told me he fixed issue and the data usage would go back to where it should be. Nothing has yet happened, my data at time of this posting is 1080gb. I messaged chat for them to pull up chat transcript to verify what was spoken but nothing.

No, we cant. Once again, an employee has posted a web address the is only accessible to employees with access to Comcast's internal, private Intranet, and NOT available to customers. Perhaps the employee meant to post the page located at https://spa.xfinity.com/?

I got my first ever "You're getting close to exceeding your Internet data plan" email in. My data usage has doubled and tripled in the past 2 months. Yet nothing has changed in how I've use this service in years. I have one device, my computer. I don't use any streaming services or play games. I just use the internet. From an average monthly usage of 300 - 400 to jump last month to 600 and then to 1000 this month and climbing. Nothing has changed so why is my data usage suddenly increasing?
