CMU-Cylab is an academic Research from Carnegie Mellon University used for search indexing, URL discovery, page rendering, result freshness, and search-quality checks.
Its primary user-agent pattern is CMU-Cylab; related patterns include CMU-Cylab/1.0; Carnegie Mellon research crawler.
CMU-Cylab is Unverified at the identity-evidence level. The listed identity remains useful for detection, but this record does not currently contain authoritative evidence sufficient to authenticate the identity claim.
Robots.txt behavior is not currently confirmed.
CMU-Cylab should be reviewed against site policy, source evidence, crawl rate, and requested paths before a permanent allow or block rule is created.
