PMN down for updates 7/31

Edit 2: All databases are back up again

Edit: The downtime has been pushed to 7/31, same time. PMN will remain up the evening of 7/30

Original post: The PMN databases (meaning all functionality on https://pmn.plantcyc.org) will be down for updates this evening (July 30) starting sometime around 5 PM U.S. eastern time. Exact downtime is not certain but we are aiming for an hour or two at most. The front page at https://plantcyc.org will remain accessible. We apologize for the inconvenience and will update this post when the databases are back up.
