The update reads:
Thanks to everyone who tried out Facebook Lite. We're no longer supporting it, but learned a lot from the test of a slimmed-down site. If you used Lite, you'll now be taken to the main Facebook.com site.
I used to have a small notification bar atop all the pages on Facebook.com which remined me of the Facebook Lite but a sudden disappearance of the bar made me think if the service has been discontinued which actually turned out to be true! Facebook Lite was basically meant for dial-up users and since it has been discontinued now, users on slow internet connections have to revert back to the Facebook.com version of the social network. However, such users may also try the m.facebook.com mobile site of Facebook on browsers. There is another light version of Facebook called the Facebook Zero, but this version is available strictly from Mobile devices.
