It is the MOMA login page :) From my time at google (around 6 months ago), you can access this page for a lot of services, but some of them will be accessible only from the intranet (or if you login to a VPN from the internet). What has changed is the number of services that are now accessible from the internet.
Also, when I was working there, I could not remote into my desktop from my company laptop from my home without signing onto VPN. Not sure of that has changed, but they wished to phase out VPN completely.
