AI crawler access behind Azure Front Door
24 of the 292 origins measured in this segment disallow at least one answer engine at the site root, 8% of the segment. That answer-engine rate is 1.2 times the corpus rate of 7%, which is itself measured across 30,223 domains.
Mean AI access score across those 292 origins is 75.4 of 100, 26 of them publish an llms.txt (9%), and 120 publish structured data an answer engine can parse (41%).

Block rate is the share of this segment's domains holding a policy record for that agent whose robots.txt disallows it at the site root, shown with its numerator and denominator. Denominators differ between agents because a record only exists once a domain has been measured for it. A domain serving no robots.txt counts as allowing everything, which is what the standard specifies.

Compare with the rest of the grouping edge provider segments
The largest 10 other segments in this grouping, ordered by size. The share beside each is that segment's own answer-engine block rate over its own count. Full table on the segments index.
What this segment does not tell you read this before citing it
Only providers that expose an identifying response header can be detected. Sites behind an edge that stays quiet, or behind an origin that strips those headers, are absent from the count, so this sample is not representative of any provider's customer base.
Measure your own domain
The audit that produced every number on this page runs on any domain in about six seconds: robots.txt resolved for 48 agents, then live requests sent as four of them to see whether the edge agrees with the file.
