Until yesterday, we had gone over a month without any interruption in service, ever since we migrated to the new high-end datacenter. If you have been experiencing ongoing cart problems within the past month, then there is something amiss with your particular configuration; all of our other Merchants have been in operation just fine the whole time, and since everyone's service runs from the same software, any problems with our service would affect everyone, not just one or a few Merchants. Please send us a message describing what problems you are having, so we can help you remedy your configurations:
In fact, all of our own systems continued in full operation yesterday without a hitch; the problem was that the rest of the Internet started forgetting how to find us, and our DNS provider refused to continue reminding them. What happened yesterday had nothing whatsoever to with our servers, nor our datacenter, nor our software/scripting/programming, which all remained fully functional the entire time. What happened to us could happen to any site that doesn't operate their own DNS server -- namely, the vast majority of sites out there, almost certainly including all of yours. No matter what uptime stats you or we or anyone can claim, when the company that provides your ".com" domain name's DNS service decides to stop rendering that service, your site simply drops off the map and vanishes from the face of the Web; even though your server's uptime stats would continue uninterrupted, that doesn't matter when nobody's computer knows how to contact that server anymore.
So that's what happened, and that's why we're growing some serious nerd brass by assuming operation of our own DNS right here in-house, so that never again could we and our Merchants be held hostage by a third-party upstream provider beyond our control, as happened yesterday.
