In order to keep Nexus IQ Data Services performing at an optimal level, Sonatype performs scheduled maintenance twice a month on the 1st and 3rd Saturday of each month, from 13:00:00 to 15:00:00 EST/EDT.
Often times the maintenance will not impact the service; however, If service is impacted, it will be noted on our official Sonatype status page: https://status.sonatype.com
If there is a need for emergency maintenance outside of the scheduled windows, it will be noted on https://status.sonatype.com
