A couple of direct hits to my robots file as well as a non-visible pdf file on my site yesterday from a couple of different IP's in 72.30.14.0/24. These IP's belong to Inktomi but reverse to something.crawl.yahoo.net.
This is the same pdf file that qualityassurance.siteimprove.com (93.160.60.0/24) also likes to access for some reason, for which I have a block in place for, and for which coincidentally it too also tried to access yesterday.
Looking back through 8 years of log files show a grand total of 302 hits from 72.30/16 starting Dec. 2011, all of them showing a Yahoo Slurp user agent (but sometimes the UA is simply LLF). These hits practically ended in August 2013 but the last 8 of them happened Aug/Sept 2017 and Yesterday.
Just mentioning this because of (a) the rarity of seeing Slurp operating from 72.30/16 and (b) having a primary focus on a private pdf on my site that coincidentally is of interest to (c) siteimprove.
