Tor Atlas informs me "No results found. No Tor relays or bridges matched your query" But when I use find my ip location tool I am shown to be exiting in another country. I worry that I am exiting through a fake exit node.
Atlas had some problem in the last days. It seems that the backend onionoo was not working properly. This also affected Globe. It works properly now. So you should check if still you get the message from Atlas.
Another possibility to check if an IP address was a Tor relay is Exonerator. Just enter the address and a date and it will tell you if it was an exit during this time.
