An emergency shutdown is a rapid and controlled termination of server operations in response to a threat or issue. In contrast to a scheduled shutdown, which is conducted for technical maintenance or hardware upgrades, an emergency shutdown is initiated without prior notice and with minimal delay due to the urgent need for action.
Let's take a closer look at what an emergency server shutdown is, when and who might need this service.
Why an emergency shutdown is important
In the event of an emergency, such as a fire, equipment malfunction, power failure, hardware or software failure, or cyber-attack, servers may require an immediate shutdown.
It is essential to implement the procedure to prevent data loss or compromise. As an illustration, in the event of a potential database breach, an emergency shutdown can prevent the attack and safeguard sensitive information.
Another significant concern is the potential for hardware failure due to overheating, fire or other catastrophic events. A server shutdown prevents damage to GPUs, disks, switches and other critical components. In the event of a significant threat, an emergency shutdown minimises disruption by preventing damage to hardware and data, allowing for a faster return to normal operations once the threat has been resolved.
Emergency shutdown of physical or virtual servers is necessary for different businesses.
-
International corporations and government organizations depend on their IT systems, so ensuring the safety of critical data and equipment is a priority.
-
Banks and other financial institutions manage customer accounts and process millions of transactions daily. It is essential that they are able to shut down servers rapidly in the event of a threat in order to prevent data breaches and financial loss.
-
Hospitals and medical facilities store and process sensitive patient information and use electronic medical records. It is essential that they respond rapidly to any type of risk in order to protect data and guarantee the continuity of healthcare services.
-
Online shops and retailers manage extensive customer databases and process a considerable volume of online orders. Consequently, these organizations are seeking to safeguard their servers from cyber-attacks and other threats.
-
For data centers and cloud providers, emergency server shutdowns are also a necessary measure to ensure the security and continuity of business operations.
Emergency shutdown - case studies
Throughout history, emergency server shutdowns have proved an effective means of avoiding significant difficulties for companies.
In 2013, a fire broke out in the data center of one of the largest cloud service providers. It was imperative that all servers be shut down immediately to prevent the fire from spreading and minimize damage.
In 2015, lightning struck one of Microsoft's data center buildings. This resulted in a power outage and the potential for equipment damage. The staff promptly initiated a server shutdown to prevent overloading and subsequent equipment failure. The company was able to avoid serious damage and quickly restore services thanks to its rapid response.
In 2021, a fire incident occurred at one of OVH's data centers in Strasbourg, France. Upon detection of the fire, the company's staff promptly initiated the shutdown of servers and activated the emergency plan. This prevented damage to data and equipment in neighbouring buildings and minimized financial loss to customers.
In 2014, Sony Pictures was the victim of a large-scale cyberattack. To prevent further data loss and damage to infrastructure, the servers were shut down.
In 2019, Capital One Bank experienced a severe cyberattack that resulted in the theft of the data of millions of customers. Upon identifying the breach, the bank's experts initiated the shutdown of its servers. The bank was able to limit the extent of the data loss and promptly initiate the necessary remediation activities to address the vulnerability.
In 2012, Hurricane Sandy caused considerable damage in New York City, where a large number of data centers are situated. The servers were decommissioned to safeguard the equipment and data from potential damage caused by flooding and other adverse conditions.
In 2017, Hurricane Irma had a severe impact on infrastructure in Miami, hitting the south-east coast of the US. In response to the situation, one of the data centers in the region decided to shut down servers and evacuate staff. This reduced the likelihood of hardware and data failures. Once the infrastructure was restored, the company was able to resume normal operations without a delay.
How to prepare for a shutdown procedure
The termination of a server constitutes the final stage in a series of procedures. It is risky to shut it down without a valid reason, so we advise to be prepared for this event (which may not occur).
Develop an action plan. It is essential that every organization has a clearly defined emergency shutdown plan in place, outlining the sequence of actions to be taken in the event of an incident. It would be an effective approach to create a document that details the procedure for safely shutting down servers and assigns responsibility for each step of the process.
Staff training. Regular training of staff responsible for emergency server shutdowns will help them respond quickly and effectively to threats.
Monitoring. The use of monitoring systems for the early detection of problems and threats will allow you to respond to an incident in time.
Data backup. Regularly backing up data and storing it in an off-site data centre will help minimise loss in the event of an emergency server failure.
Regular system audits. Testing and regular review of system performance and timely updates will help ensure their relevance and efficiency.
