Sudden Spike in Data Usage

Hello, 

I usually use around 500GB per month, but my data usage has suddenly spiked up since December, 2024. It seems almost doubled than I expected. 

For the December, 2024, I waived the data overage fee because of it's the first month of over 1.2TB limitation. In January 17th, 2025, I received a warning message that I've used 75% of the limitation. So, I added unlimited option ($30) to avoid the overage fee, just in case if it is over 1.2TB. Then, I found that there are many users that have the same issues on this forum:

Also I found that, there is a known issue like the attached screenshot below:

What should I do?

Following this since I'm having the same issue. Usage spiked by 4x. I was chatting and on a call with xfinity for over 5 hours yesterday and no one was able to offer any help or even acknowledged that this is a known issue for other users that they're investigating.

@XfinityAngie​ The same thing is happening to us.  We typically averaged around 700 GB per month in 2024 and in January 25 our data usage went up to over 1000 GB.  When will this problem be fixed and should I call to add our account to having this issue.  We have cut down on our use, because we worry about going over.  We cannot afford to pay another $30 per month for unlimited data.

@XfinityAngie​I just posted that the data usage has gone up in January 2025.  This is what our usage was in 2024.  We are two senior citizens with no other users living with us.  Our typical daily data usage is around 28 GB.  We would appreciate knowing if you can fix this problem and when we can expect our data usage totals to go back to those on this chart.

@user_0dhvzo The reply the poster is referring to is from October 10, 2023. If you're experiencing some ballooning in your data usage, we would advise disconnecting all devices from your network and change your WiFi password. After reconnecting your devices with the new password or physical cable, you would want to check the devices that are connected under the WiFi tab to ensure no devices are connected that you do not wish to be on your network. You can connect one device at a time and test if you're seeing a big amount of data after a few hours. This will isolate any devices that are connecting and attempting to download data at a higher rate. Resetting the WiFi password will also remove any devices you did not authorize to be connected.

Have there been any successful resolutions to this issue? This definitely seems like an Xfinity GB usage calculation change as no way this many people have same sudden spike in data usage.

I have been experiencing the same since mid Dec 2024 with monthly data usage almost doubling. No change in devices and even reset WiFi password in case there was unauthorized activity on my network (which seeing this thread is clearly not the case). I will be calling customer service this week and canceling (move to a different provider) if a remedy can’t be reached as this type of rouge treatment to customers who use their own modems (as an attempt to force into XFi modem) is low, even for a utility company

I'm having the same issue, random data spike for the month of March and have gotten zero assistance with this from "customer service", or any of the other numerous departments I've been transferred to for the last 8 days spending literally hours on the phone each day.  Problem is not on my side and Xfinity seems incapable of solving this issue or even telling me why it is happening.  Unacceptable.  If it's some kind of fraud they are participating in letting it continue.
