"Continuing" vs. "continued"
Solution 1:
There is a slight difference between the two.
Use continued when you are speaking about availability that has persisted up till a point in time (e.g., now) but may not persist past it.
Use continuing when you are speaking about availability that will persist into the future.
Solution 2:
"Continuing" is the effort make whatever ongoing into the future but may stop any time and for any reason, "continued" refers to picking up where is left and not moving forward and you make it move and keep it going.
