ZZZ1 Center had a positive COVID test from an individual in their building. The decision was made to go ATC-0 in the middle of the afternoon to perform a Level 3 cleaning.  I would completely understand the need to do the cleaning immediately; even if it was a high traffic time; if the individual had started not feeling well during that shift; or during the any shift in the previous 24 hours.  This was not the situation here. The positive test came from an individual that had not been in the building in X days!  Every Controller that had worked in the previous X days already had worked in a potentially contaminated area. There was zero benefit to go down at that time. The decision makers did nothing that was reasonable and responsible in this situation. Reasonable and responsible would have been to wait for a slower traffic period to get the clean accomplished. I had Aircraft X that had been in the air for 15+20 hours. I was forced to route him over an hour [out] of his way which put him in a minimum fuel situation.  We had MedEvac flights; on critical missions that were not allowed to pick up their patients.  I would hate to know how many passengers missed their connecting flights. We put our controllers; pilots; and flying public in an unnecessary unsafe situation.When an individual has not been in the building in the past 24 hours DO NOT CLEAN during a high traffic period.
Center Controller reported an adjacent Center going to ATC Zero due to COVID-19 cleaning and having aircraft that were not allowed on filed routes.
