Requests observed to this server indicate it was accessed by the Moz DotBot automated web crawler.
Moz' 'DotBot' recently discovered and indexed web content available on this server. Crawling is the process by which various search engine bots discover new and updated pages to be added to their search results. These automated scans are conducted regularly (or periodically) to peruse the entire public IP space (including domain listings) in order to update their search results.
Determine if the affected service or content should be externally accessible. In the event this server cannot be removed from the public realm, consider implementing 'robots.txt' to help limit automated bots from scanning sensitive zones within the site.
