The website may go down here and there over the next few days.
The upgrade process is proving to be a lot harder than expected this time around because of how many servers and programs that need to be updated. Many of these are general system security patches that have nothing to do with the website directly. But they cause issues with base system operations and can cause the website to stop working.
We will try to keep these to a minimum but sadly they cannot be avoided. Some systems are fighting with other systems during the upgrade process.
Thanks for your understanding.
