Pivotal Tracker will be down for an infrastructure update for 45 minutes, starting at 7pm (MDT) on Friday, April 13, 2018 / 1am Saturday, April 14, 2018 (GMT).
After the update you will need to sign in to Pivotal Tracker again. You should be redirected to the sign in page, but if not you can find it here: https://www.pivotaltracker.com/signin
Other than this, you should not notice any difference in using Pivotal Tracker after the update.
