This has nothing to do with the update and goes way beyond what a patch could cause. The official website is having problems. The homepage shows all stats at zero. The Events page is empty, and the Leagues page throws a 500 error. 500 internal server errors are generally serious breakdowns. Sometimes they can be fixed by a server reboot, and sometimes they can be caused by catastrophic data loss. In between would be maybe a hanging server, or a coding error that causes the webserver to fail to interpret what we are requesting from it through our browsers. I suspect there is something wrong with the RaceNet database. The DB is where all our times, results and stats are stored, so when the official site is showing all stats at zero it is definitely not good news. It might just be a networking hiccup between the webserver and the database, or could be as bad as a catastrophic loss of data in the DB, or somewhere in between.
If the issue means that all our stats are wiped out, I am quite sure that Codies would have a backup of everything. Personally, on every web site or application I design, I run automatic backups every 24 hours of webserver files as well as database tables. If I were running RaceNet I would ensure that those backups were being taken every five minutes at the very least.
Let's hope that they can get it sorted soon.
BTW, as kind of a prelude to this outage, my second league event finished late Thursday night. Friday morning, just before the problems started, I noticed that no-one was awarded points for finishing. The results were logged, but the championship standings were not updated. I suspect that the breakdown was already underway at that point.
