Talked to MagicalTux and one of their systems had issues. I don't know the status about that atm, but downtime should be reduced when the system goes down again (lets hope it doesn't). Advertisers have been compensated for their lost credit.
And now for the good news:
I've pushed a new interface to the users with new features. Although it should work fine, if you experience problems, please let me know.
Some new things:
General: Ads can be marked as animated or X-rated by the Advertisers (and if they don't do that I will, but that can take time). Site owners can indicate if they allow these types of ads and websites can have a default policy (reject not-yet-approved ads or allow them).
Publishers: New website interface (with stats, approval of ads, ability to change settings, etc.)
Advertisers: Warning when you try to bid on a site that you have no compatible ads for. New website selection screen for placing a new bid.
This was a pretty invasive update for the code base and server, so that is why it took so long. I can now focus on more smaller updates for features and suggestions that people have send me.
