@kidx: it doesn't actually uninstall, if your server/host can't talk on one of the selected protocols to xortify.com it will disable the system xortify temporarily until communication resumes so you don't experience massive amounts of lag and slow page refreshing cause the typical DNS lookup doesn't timeout for at least 20s and if xortify.com is down it could be doing this upto 3 times in the load, which is a total of 60s delay in loading the page, which normally cause we have it on a snappy server is oftern done in under 1 second, which it will only lookup for each individual user of IP, Netaddy, Email, Username once on the system every 24 hours by default.
I hope that has answered your question.
