QUESTION

I noticed that our Cloudflare logs are dropping. However, it doesn't look like Cloudflare is failing to push logs. We are also getting the following alert in Panther:

"Source [CloudFlare-YourLogSource] has not received events for more than 1 hour" 

ANSWER

If you experience this delay, it could indicate Cloudflare issues:

If all your other sources based on S3 were fully functional, it seems more likely that Cloudflare delayed sending logs to S3, rather than the logs being dropped. You can confirm this by performing a search for events during the affected periods.
