http://detectportal.firefox.com/ is hammering our firewalls

In our environment we have many hundreds of clients/visitors that heavily use the web. Needless to say that Firefox is one of the most used web clients. :-)
We noticed a continuous hit on our firewalls which took it's toll on the cpus as the request to hhttp://detectportal.firefox.com/success.txt is from every Firefox browser installed on the desktops/laptops/etc every 3 seconds or so. ](*,) As a workaround we've allowed through the firewall an ever growing list of IP addresses and that is plain ridiculous and simply unmanageable.
Are your network gurus/engineers going to implement solutions such as anycast to alleviate this flawed implementation of a simple service as it has been in use for quite sometime now by for example Apple, Google, etc... For example if you ping 22.214.171.124, it's very likely hosted in a datacentre near your town. Will you consider anycast towards detectportal.firefox.com?
Please advise. Thanks in advance.

You can set network.captive-portal-service.enabled to false on the about:config page or use mozilla.cfg to lock this pref to false.
// lockpref("network.captive-portal-service.enabled", false);

Really appreciate the update. Our local software dev gurus sure will make use of this info towards our desktops/laptops. But as we have visitors and lots of them, they do bring their own devices. Perhaps there is a better solution (maybe anycast dns) your network gurus could come up with? Thanks in advance.
