Folks, we had a little server problem on one of the frontends just about 10 minutes ago. Let me give you a short update this way:
One of the frontend webservers failed and dispite our efforts to redirect the traffic automatically the redirection partly failed and we had some problems delivering pages on one of the cluster nodes. That could effect a few sales, when notifications from Paypal ended up without response on exactly this machine.
We are investigating right now, what happened. The traffic is now redirected to our other servers while we dig through the error logs. The platform is back at 100% delivery and the outage was only partly effecting the site for less than 30 minutes!
Sorry for that, we do our best to improve!
Update: everything back to normal, server back in operations!
