A technical issue is causing some websites to become unresponsive due to an excessive number of requests made to them in a short period. This phenomenon has been observed as ‘Too Many Requests’ errors.
When this occurs, the server cannot handle the volume of traffic and begins to return error messages, usually a 429 status code, indicating that the request limit has been exceeded. The cause of this issue can vary but often involves malicious activities like automated bots or scripts designed to flood websites with requests for data extraction.
To mitigate this problem, website administrators are advised to use security measures such as rate limiting and CAPTCHAs (Completely Automated Public Turing tests to tell Computers and Humans Apart) that distinguish between genuine users and malicious scripts.
