Every year, the worst dev experience comes right at the holidays, when website owners with big egos want to launch right on (U.S.) Thanksgiving Day, Christmas Eve, or New Year’s Eve/Day because they think they’re that popular and important. It never occurs to them that this is the WORST time because any third party support you need for hosting, APIs, plugins, etc. is either backlogged or out of office. And because NOBODY is eagerly awaiting the redesign of ANY website on those particular dates since they are stuffing their faces and getting s&&&faced at bars and parties. Nobody will even notice that your website has changed until January 15th at the earliest.
