The dev team for my company’s website was investigating some mysterious website crashes we’ve been having.
They found an extremely high number of incoming requests within a short period of time (‹1 minute) for file accesses (=GET). All of them were related to downloading media files ~ 2GB.
All the requests had the parameter '_kx' indicating they were coming from links embedded in Klaviyo emails.
My question is: how do I go about tracking down where these requests are coming from? And how do I prevent this from happening in the future?

Hello John,
The issue you're facing is likely due to a large number of recipients clicking on media file links in your Klaviyo emails simultaneously. The _kx parameter indicates these requests are generated from Klaviyo’s email links, which helps track engagement.
Steps to Address the Issue:
Identify the Source:
In Klaviyo, go to the campaign or flow that includes the media file link.
Check the email’s analytics to identify which email or audience segment triggered the spike in downloads.
Mitigate the Load:
Host large files on a dedicated content delivery network (CDN) to handle high traffic efficiently.
Consider replacing direct file links with a landing page where users can download the file manually or request it via email.
Prevent Future Spikes:
Add a download limit or implement rate-limiting at the server level to control excessive requests.
Use expiring links or token-based access for media files to ensure better control.
If you need help implementing these solutions or setting up preventive measures, feel free to reach out. I would be happy to assist and make the process easy to understand!
