Starting on August 12th we had about an 800% increase in the amount of Data Transfer Out from AWS S3 which has caused our billing to skyrocket. The amount of data has continued to be at the 800% rate every day since. Pressable (help@pressable.com) has said “The two FV Player plugins (fv-player, fv-player-pro) were both updated on August 11, and there are some crons related to FV Player’s cache which we are suspicious of. I have multiple people working on this to find a way to stop the excessive data transfers and they feel it is FV Player. Please reply as soon as possible so we can fix this issue. The cost to us is WAY OVER our normal monthly bill.

Hello Sherri,
I would recommend that you enable the access logs on S3 to see if there’s anything specific about that increased traffic. It might be coming from a specific IP range or to a few videos only.
We did run into similar issue with Cloudfront in the past. It was really just a single video that was accessed by many IP and it was not related to FV Player. We ended up adding a limit to AWS billing using one of their built-in tools.
We did upgrade the HLS.js library in FV Player on 2025-07-11. We had a user complaining about some video buffering issues with it an upgrading the HLS.js library helped. So if you post videos in the HLS (m3u8) format, upgrading FV Player might help.
Other than that I did not find any other change that might cause this. There are background jobs (crons) in FV Player which check the video duration, but they only run once for each video and were not changed for years.
Thanks,
Martin
