A good professional practice is to post all information about the system status. Ebay does not.
Here I tried to refund a buyer, who paid twice for the shipping. I get an error. Contacted the support, they confirmed it doesn't work since 2 hours. Why they just not post that info on their website?

Here an example how a responsible company handles such a situation. VPS being down is very serious, and they are not afraid of admitting they have a problem. Ebay - please post info on a system status page - people will stop to call your technical support if they can find an adequate info there.
