We're planning a quick maintenance window tonight (Friday-US) to enable a few new features.
The Sandbox's Web Portal will be down, but access to active labs will remain undisturbed.
BEGIN: 10:00PM Pacific Time, Friday, March 20, 2015
END: 02:00AM Pacific Time, Saturday, March 21, 2015
We apologize for any inconvenience this may cause.
Thanks for playing in the sandbox with us!
