Based on the existing answers, it appears that the question is referring to Vercel rate-limiting certain IPs for no apparent reason. This could be due to a variety of factors, such as a high volume of requests from a specific IP address, or a suspicious pattern of requests from the same IP address. In either case, Vercel may be attempting to protect their system from malicious activity by limiting access from certain IPs. It is important to note, however, that rate-limiting is not always necessary and can be a nuisance to legitimate users, so it is important to make sure that the IPs being rate-limited are actually engaging in suspicious activity before taking any action.
