FB ADS Sudden no visitors

Hey everyone! I wanted to ask because I see that no one else seemed to complain which is kind of bad ... or good I don't know.

I started to run a CBO test campaign 2 days ago as usual and got 0.20-0.30$ cpc as usual once again and as of midnight the day after, almost no visitors and general cpc of 1$-1.20$. So first day I got 52 visits and now I'm getting like 15 visits and I have no idea if its because of the elections or what not.

Should I worry? Don't know if I should stop everything.

The Facebook office is currently under fire as you can see in the image above, your problems will be solved ASAP.

Anyone knows why it would radically change after a day? Is it because the ad is optimizing? Had a great cpc first day and 2 sales and now its soooooooo slow for 2 days! If its normal than be it but I'm trying to know if something else is not working and need to stop the ads and start again. Anyone with this experience?
