Facebook In Stream ads RPM sudden drop by over 90%

My RPM dropped by almost 93% in last 3 days as compare to the first half of the month… to be spefic, its 0.03$ and mostly us uk traffic. I have never seen it this low before… the content is 100% original. one video takes us weeks to make and went viral but all of a sudden the RPM dropped…
I haven’t made any changes to the page or have ads off or disable …
Anyone has any idea whats happening here… any help or sugguestion are highly appricated. Thank you
