Separation of concerns

I came across a scenario where the login functionality is in the home page itself. It worked fine for 3+ years in production until we came across an outage due to issues in code that also got the home page down.

Now, the login page would be separated from the home page, and the login page would encourage user to bookmark it. This way the bandwidth requirement would also come down as the home page would not be accessed by regular users over time.
