All hardcore servers are gone?

Hi.

For whole last week I played only hardcore (thast what I only play in BF) on one of those 64/64 HC servers that I joined through server browser. Today I check server browser and all of the hardcore servers are  gone. There are no more conquest servers and if I join any server that says hardcore it is not hardcore. There is hud no friendly fire minimap crosshairs etc.

What happened to all the hardcore servers and how can I play them again?
