Editing 24/7 service (section)

==Service disruption==
In some cases, 24/7 services may be temporarily unavailable under certain circumstances. Such scenarios may include [[scheduled maintenance]], [[upgrade]]s or [[renovation]], [[Maintenance, repair, and operations|emergency repair]], and [[injunction]]. 24/7 services which depend upon the physical presence of employees at a given location may also be interrupted when a minimum number of employees cannot be present due to scenarios such as [[Weather-related cancellation|extreme weather]], [[death threat]]s, [[natural disaster]]s, or [[emergency evacuation|mandatory evacuation]].

Some 24/7 services close during major [[Public holiday|holiday]]s.

===Redundancy and hardening===
24/7 services often employ complex schemes that ensure their resistance to potential disruption, resilience in the event of disruption, and minimum standards of overall reliability.

Critical infrastructure may be supported by [[failover]] systems, [[electric generator]]s, and [[Communications satellite|satellite]] communications. In the event of catastrophic disaster, some 24/7 services prepare entirely redundant, parallel infrastructures, often in other geographic regions.

===Long-term post-COVID disruption===
At the beginning of the [[COVID-19 pandemic]] in 2020, many stores ended 24/7 operations, ostensibly on a temporary basis, in order to clean and sanitize their establishments.<ref name="Biz Insider COVID" /> After the widespread availability of vaccines, however, many such businesses have not returned to 24-hour service for a variety of reasons. Some proprietors in the United States originally blamed pandemic unemployment benefits for a lack of workers, yet employers still struggled to resume pre-pandemic hours after these programs ended, citing continued staff shortages and demands for better working conditions among jobseekers. Many businesses that were once broadly open for 24/7 operations only resumed such service across some of their establishments or have ended 24/7 operations altogether, as in the case of [[Walmart]].<ref name="Biz Insider COVID">{{cite news |last1=Meisenzahl |first1=Mary |title=Walmart, 7-Eleven, and McDonald's shortened hours during the COVID-19 pandemic, and 24 hour shopping might be slow to return |url=https://www.businessinsider.com/covid-ended-24-hour-shopping-walmart-7-eleven-mcdonalds-2021-5 |access-date=16 February 2023 |publisher=Business Insider |date=16 May 2021 |archive-url=https://web.archive.org/web/20210520035726/https://www.businessinsider.com/covid-ended-24-hour-shopping-walmart-7-eleven-mcdonalds-2021-5 |archive-date=20 May 2021}}</ref><ref name="Forbes post-pandemic">{{cite news |last1=D'Innocenzio |first1=Anne |title=Frustration mounts as customers want longer opening hours, stores can't fill positions, employees feel overworked: 'Nobody is winning' |url=https://fortune.com/2022/12/11/post-pandemic-frustration-shoppers-workers-business-owners-opening-hours-service-holiday-shopping/ |access-date=16 February 2023 |agency=Associated Press |publisher=Fortune |date=11 December 2022 |archive-url=https://web.archive.org/web/20221222071548/https://fortune.com/2022/12/11/post-pandemic-frustration-shoppers-workers-business-owners-opening-hours-service-holiday-shopping/ |archive-date=22 December 2022}}</ref>
