We are aware of ongoing issues with the CS department website. The problem began shortly after midnight when both our main web servers got into an irregular state and had to be rebooted. Now parts of the website are back, but the home page itself (https://cs.brown.edu/) refuses to load properly. Possibly other pages are broken.
We are still investigating the cause and doing everything we can to bring back the website quickly. For the time being, hold off on attempting to update any dynamic pages such as user profile pages.
This post will be updated as we learn more.
EDIT 9:40am - The website is working again. It's not clear what the original problem was around midnight, but the lingering problems with the home page arose from unexpected issues parsing the University's event feed. It should be safe to edit pages now. -bnacar
