Microsoft has started pushing security updates for SharePoint along with windows update. If you are using automated patching tool , then you should be aware of this. Same thing happened to me. Our automated tool pushed through patches for share point security
update that needed SP1 as pre-requisite and our environment didnt have that. So it broke everything in all farms, 5 farms broken all together. What you can do is try to install any new security update . This will restart all the process of patching and make
your farm accessible. 
I opened up a support ticket with microsoft so August security update broke my farm so just to fix it i had to install may security update for the shake of restarting the  whole prcoess. If fixed the farm. I eventually ended up installing SP1 any way
since security update introduces office 365 tab in central admin and it was broken due to lack of SP1.
hope this helps.
