There are reasons to prefer a Friday over other days as well, but the internet doesn't schedule around random participant's personal preferences. Besides, its a substantial misrepresentation of what the DNS Flag day is to describe it as a "breaking change" made on a certain date - changes won't finish in a week, changes won't finish in two weeks --- every day of the week may be affected until the gradual process of every OS and DNS vendor releasing and every end user upgrading finishes. Each software vendor and service provider will have their very own update schedules regarding on what exact date the next version release and every manager of a system with a DNS Resolver software installation will have their own choice on when they actually install the next update at their site. Just because all the major maintainers of DNS resolver software agree all releases after tomorrow will remove the workarounds for broken DNS servers/firewalls that silently discard queries does not mean every software vendor is shipping their new code to release on Feb 1, _and_ every end user is rushing to upgrade their DNS resolver to remove the workarounds. -- -JH
