We had a DDoS attack to our servers, they were offline for 24 hours. Our server was deleted from Gametracker for some reason? We have lost all our data and our crazy high rank? Sigh.

Had to recreate it, any chance of restoring it?

Servers are automatically removed after extended downtime. Your server would have only been deleted so quickly if it was only on the site for a few days. In this case, you will need to regain your rank. Luckily, rank only ever looks at the past week of data, so if your server is just as popular, it will take no time to recover.
