before the huge dive this what happened on the google console. DNS was flagged red.
the backlinks are all citations and local directories that have consistent NAP which I am also careful in choosing.
----update
suddenly the rankings went up after 3 days and are back. I noticed it after I search for the business brand name and the result showed our domain name. So I fetch and render the site on google console.
It was really strange since I didn't received any message from google console about a certain penalty if it was link spam, or content.
It still bugs me and I need to find out what happened on that huge dive so that if it will happen again I will know how to resolve it quickly.(or if others will experience it and who are reading this thread it might also help them)
so what really happened?
