Technical Note
When Whitespace build your new v11 site from your ‘uat’ site we will in fact create a new server and when configuration and testing is complete we will point your URL at this new server and let you know when this is complete.
Your old server will then then be deleted securely. This process is well established and robust, but can suffer from DNS Propagation delays. These happen because of the way the web is built, with servers around the country and around world caching server information to make access faster. However, when we change the server, it sometimes takes time for the caching to be flushed through on internet servers that are outside our control.
This can result in delayed availability and Gateway 500 errors when you access your Whitespace or API system. The delay is normally less than an hour, so when you are first notified that your new system is Live, don’t raise tickets if at first you have Gateway errors, these are very likely to be DNS Propagation delays that will sort themselves out when the internet catches up.
