Hi,

Lately, when I visit codeforces.com or submit a solution during a contest, the screen goes white and a message "redirecting ...." occurs. After closely observing this, I noticed that the redirection was to a different URL, although within the codeforces domain only: https://codeforces.com/?f0a28=1.

This is particularly irritating when submitting the solution since you have to do it again after it redirects.

Does anyone have an idea why this happens?
