Don’t Get Down on Downtime

Written by Alex Locatelli, Chief Technology Officer

There are a number of reasons why downtimes happen; but it’s only the unscheduled downtime which can be very stressful. Interestingly, regular scheduled downtimes to undertake work can mitigate crashes and un-scheduled downtime…

Here's a look at why downtime occurs, what you can do about it, and some ideas on how best to manage it. 

Why Does Downtime Occur?

Planned or unplanned, it’s safe to say downtime will occur for your business. Here are some common reasons why downtime might occur:

Planned Downtime

1. System Maintenance: Routine updates, patches, and upgrades to software and hardware to ensure system stability and security.
2. Infrastructure Upgrades: Enhancements or expansions to IT infrastructure, such as installing new servers, increasing storage capacity, or upgrading network equipment.
3. Data Backups: Regularly scheduled backups of critical data to prevent data loss and ensure recoverability in case of an incident.
4. Compliance Audits: Periodic testing and auditing of systems to meet regulatory requirements and ensure adherence to data protection standards.
5. Software Upgrades: Implementation of new software versions or features that require downtime to integrate and test.
6. Disaster Recovery Drills: Scheduled exercises to test and refine disaster recovery plans and ensure preparedness for potential emergencies.
7. Performance Tuning: Optimisation of systems and applications to improve performance and efficiency, which may require brief downtime.
8. Moving operations: When businesses move warehouses, offices or relocate, it often requires downtime to accommodate for the time to move items, and then reset for business operations continuation. 

Unplanned Downtime

1. Hardware Failures: Unexpected malfunctions or breakdowns of physical components like servers, hard drives, or network devices.
2. Software Crashes: Sudden failures or bugs in software applications that disrupt normal operations.
3. Cyberattacks: Security breaches, such as ransomware or DDoS attacks, that compromise systems and necessitate immediate response and recovery.
4. Network Outages: Disruptions in connectivity due to issues with internet service providers or internal network problems.
5. Power Failures: Electrical outages or fluctuations that impact the functionality of IT systems and data centers.
6. Human Error: Mistakes or accidental misconfigurations by employees that lead to system failures or operational interruptions.
7. Data Corruption: Issues with data integrity caused by system malfunctions, software bugs, or other unforeseen problems that affect data usability.
8. Environmental Factors: Unforeseen physical factors such as fire, flooding, or extreme temperatures that impact IT infrastructure and operations.
9. Understanding these reasons helps businesses prepare for and manage both planned and unplanned downtime effectively, ensuring minimal disruption and maintaining operational continuity.

Expect The Unexpected

Having a plan to fall back on is step one to ensuring calm management and processes during either planned or unplanned downtime. For most businesses, planned downtimes occur outside of office hours to minimise disruptions, however, we’ve come up with a list of ideas to better help you manage your downtime… however it arises. 

For Planned Downtime:

1. Develop a Detailed Downtime Schedule: Create a comprehensive schedule for planned downtime that includes maintenance windows, software upgrades, and infrastructure changes. Communicate this schedule to all stakeholders well in advance to minimise anxiety.
2. Implement Redundancy Solutions: Utilise redundancy for critical systems and services. For example, use backup servers, redundant network connections, or failover systems to ensure continuity during maintenance.
3. Perform Regular Backups: Schedule regular, automated backups of critical data and system configurations. Ensure these backups are tested and easily recoverable in case of issues during planned downtime.
4. Conduct Impact Assessments: Evaluate how planned downtime will affect different business functions and plan accordingly. Ensure that any dependencies are identified and managed to minimise operational impact.
5. Notify Stakeholders: Communication and leadership is often the most important aspects of reducing the stress and impact of downtimes. Inform customers (if necessary), employees, and partners about scheduled downtime well in advance. Provide details on how the downtime will affect services and offer alternatives if possible.
6. Test Procedures: Regularly test your maintenance and upgrade procedures in a controlled environment to identify potential issues before they impact live systems.
7. Document Processes: Keep detailed documentation of the procedures for performing planned maintenance. This ensures consistency and helps in training new team members.

For Unplanned Downtime:

1. Develop a Disaster Recovery Plan: Create and maintain a comprehensive disaster recovery plan that outlines procedures for various types of unplanned downtime, including hardware failures, cyberattacks, and natural disasters.
2. Implement Robust Monitoring: Use monitoring tools to detect and alert you to potential issues before they escalate. Proactive monitoring helps in identifying and addressing problems early.
3. Establish Incident Response Protocols: Develop and regularly update incident response plans that outline how to handle different types of unplanned downtime. Ensure your team is trained and familiar with these protocols.
4. Maintain an Updated Asset Inventory: Keep an up-to-date inventory of all IT assets, including hardware, software, and network components. This helps in quickly identifying and addressing issues during unexpected downtime.
5. Create Communication Plans: Have a communication plan in place for notifying stakeholders during unplanned downtime. This includes informing employees, customers, and partners about the issue and providing updates on resolution progress.
6. Regularly Test Backup and Recovery Procedures: Regularly test backup and recovery processes to ensure data can be restored quickly and accurately in the event of an unplanned outage.
7. Train Your Team: Ensure your IT team is well-trained in handling emergencies and unplanned outages. Regular drills and training exercises can help them respond effectively under pressure.
8. Evaluate and Improve: After any unplanned downtime event, conduct a thorough post-incident review to identify what went wrong, what worked well, and where improvements can be made. Use these insights to refine your downtime preparedness strategies.

A robust set of proactive measures, tools and guides is the best way to reduce the impact of downtimes in your business. Do you need help with this?
