Currently with a dedicated server there is no way to specify a server seed. If you want to use a custom seed you will want to go into single player and created your world with your desired seed, then following the upload instructions (which can be found on your control panel) upload the world to your server.
If you want to find out what your current server's seed is, you will want to download a copy of your world via FTP and place it into C:\Users\%USERNAME%\AppData\LocalLow\IronGate\Valheim\worlds then boot up your game and you will be able to see the seed from the single player world select menu. If you need instructions on how to download your world let us know!
If your page is showing an unknown tag the data center is currently having some power issues which they are fixing. If it is showing stopped please send a ticket in and I can get you fixed up.
We are currently working on this. The data center is having a power issue which took a down a few of the server boxes. Once the power issue is corrected the servers should be back online and back to normal status.

We have noticed some issues with steamcmd lately timing out or stopping mid download. Another update/validate should fix this issue if anyone else sees a problem with it.
For our current system we do not limit the ram or cpu for connan exiles. Your server will use what it needs to run. The only upgrades we offer would be slot count. For the donating sadly not at this time.
