The shared webserver migration described in our previous post has been completed.
If you need to change DNS records, as described in that post, then you should do so now.
We are now completing a number of post-migration tasks and monitoring for any possible problems. End-of-day update: All has been running well. A number of minor issues have been identified and resolved during the day; there are no known unresolved issues. There will be no further updates; if you encounter a problem, please report it in one of our support channels in the ordinary way.
