IssueWhen a concentrator is being re-indexed, it will become offline and will only be accessible once the re-index is over.
This can take anywhere from minutes to days, depending on the size of session database (DB) in the concentrator
ResolutionIndex would reset at ~ 100,000 sessions/second on a normal concentrator, so the formula to obtain an estimated downtime is:
ETA of downtime in Hours =  (number of sessions in session DB/100,000)/3600
NOTE: The number of sessions in session DB can be obtained from:  Concentrator > Explore >  database > stats > session.total
