These are usually allowlisted rather than blocked. Monitoring traffic looks like a bot to a WAF or rate limiter, so checks get challenged or throttled and you get paged for an outage that never happened. Allowlist these ranges ahead of your bot rules. The same list also lets you identify probe traffic in access logs, or block monitoring you did not ask for.
