On Launchpad we agonize about going read-only for 60-90 minutes a month to make database changes. Waitrose, however, have quite a different idea.
They’ve built a new website:
…you can continue to shop at Waitrose.com as normal.
However, in order to allow us to transfer your details over to the new website, you will be unable to make any changes to your Waitrose.com Account, including your billing details and delivery address, between the 28 February to the 11 March 2011.
I can think of reasons why they might plan a migration this way, but I can’t think of any that actually justify it. They are mucking around with their customers - grocery shoppers - for 11 days. After which the customers will be left with a website which they can probably no longer navigate, and is likely to be full of bugs.
