Light fixture with 3 white, 3 black, 1 red wire
Well, the good news is each cable is unique.   


The /3 cable is not like the other cables, and there must be a reason for the extra hot.  Was this ever a fan/light? It may also be a new style switch loop. 
The black wire with the white tape is weird (usually it,s the other way 'round) but that tells us that the black, and its partner white, are special.  They may be a switch loop, and I would check for that with an ohmmeter after confirming power off.  
The other /2 cable is plain.  I have a hunch it's either supply power, or onward power to another location.  


Now, the question is what else is around here? Is there another light?  What's in the switch box? Etc.  

Also, what else has lost power?
