Credit cards have expiration dates. These dates come and go and new cards get reissued. This sometimes causes issues with auto-billing systems. In the case of auto-debitting accounts for webhosting at 1and1, I guess you don’t get notified before they turn your stuff off. Great customer service, right? So, I editted my payment info at 4PM Friday, as soon as I noticed my site was down (I guess it was down starting midday Thursday, but I was too busy with work to notice), and they didn’t reinstate it until just an hour ago. (8:30 AM, Monday)… Total Bullshit.
