On Wednesday afternoon, at 2pm, the Atlas offline production database (ATLR) was affected by a scheduled intervention aimed at replacing a defective redundant FC switch. The intervention which was expected to be transparent (and in the past was performed few times in a transparent way) this time caused a sequence of serious issues and ended up with database unavailability and restart of all Oracle instances.
