I’m facing an unexpected issue with my website’s bandwidth. I received a warning stating: “This site is approaching the 400 GB monthly bandwidth limit for the Business Site plan” and has reached 1.6TB despite no change in traffic.
Webflow Site Usage shows that we consumed 1.6TB of bandwidth, but in fact, my tech team concluded the total usage of top 1000 assets is only about 193.68GB - leaving over 1.4TB unaccounted for. Please see attached image:
We’ve analyzed the complete asset list and confirmed that even accounting for all smaller files, it’s technically impossible to reach the bandwidth levels Webflow is claiming.
I’ve also checked Webflow University and other online resources, and have already done the following:
Converted fonts from TTF to WOFF2
Compressed large size images
Removed unused classes
No videos on our site
But these steps haven’t helped since the high volume appears to be caused by Webflow itself.
I have contacted Webflow customer support several times but no one has responded.
The difference between your calculated asset bandwidth (193.68GB) and the total bandwidth consumption in your Webflow dashboard is due to how bandwidth is measured. The total bandwidth includes:
Hosting bandwidth (HTML, CSS, and JS files)
All user agent traffic (both human visitors and bots)
All HTTP status codes (successful requests, 404 errors, and redirects)
If you’re experiencing higher than expected bandwidth usage, it may be due to bot traffic. You can manage this by adding a robots.txt file to your site to control which pages search engines and bots can access. Learn how to implement this in our guide to generating a robots.txt file.
Hopefully this helps! If you still need assistance, please reply here so somebody from the community can help.
Hey Momo, the discrepancy is weird. I’d love to dig through those reports up close and see where the gaps are.
However in general it sounds like you’re getting a big traffic spike- there are two possibilities that come to mind.
Bots like Claude do full site downloads including all media. They tend to be very inefficient and will download everything.
SEO tools like Graphite can do similar things while you’re in the SEO editor, downloading assents on repeat. I’ve seen Webflow sites DDoSed by certain tools that have no download safeties. Leave a tool open and it just keeps redownloading.
