I have had google crawl and index my ampr.org site. I have since blocked that though, as I don't really even need what I am running to be accessible outside of the 44 netspace.
Keep in mind webservers are just one type of service. My most frequent non 44 net type of traffic is SMTP.
If you are trying to get a feel for what is out there, here is a message from a few years ago. (Note: Most are only accessible from within the network)

Ok what are people actually DOING over their Internet-connected 44 radio net?
VOIP? APRS? Video links? Repeater linking? IP cameras? Remote bases?
All of them! You might want to click around:
