A recent block by Cloudflare’s system has affected an IP address belonging to a client who made over 1,000 requests within a short period of time, as identified by the ‘too many requests’ rule. This indicates a high volume of data being transferred, which may be related to various scenarios such as brute-force attacks or resource-intensive operations. The exact nature and purpose behind these excessive requests remain unknown at this point, but it is imperative for the affected party to review their activities and adjust accordingly to avoid future blockage.
