As of Aug 24 2019 to Aug 25 2019:
The JGI Single Sign On group will be physically moving their servers to a new location!
This will affect logins into IMG/MER, IMG/Submission, IMG/ABC private and their availability.
In most cases the above sites will be down.
The public IMG/M should still be available.
Note that any JGI web site that requires login will not be available too!
Eg, downloading data sets from the JGI Portal
