I found an intersting quote by Jeffrey Zeldman tonight: What happens when a site begins to become unreliable? First-time visitors don’t come back. Regulars start to mistrust the site.
This is what’s going on right now with [DELETED]. The transaction server was finally up today after being down since September 3rd. Visitors could browse the store, pick things out, but they could not buy anything. We must have lost several thousand dollars of potential sales. I hope this never happens again, or it’s definitely time to find a new host.
