Other Technical Issues

• System updates: System updates are crucial for ensuring security and performance. However, if not performed correctly or if they are incompatible with other factors in the environment, they can lead to downtime.
• Source code conflicts: When multiple individuals work on source code, conflicts arise when they submit different versions. This can lead to discrepancies between versions and cause the system to malfunction.

Technical issues are often the primary causes of downtime in technology environments. Understanding and managing these causes is crucial for optimizing performance and minimizing system downtime.

3.2. Overload and Resource Issues

Overload due to Sudden Traffic Surge

• Sudden Events: When unforeseen prominent events or marketing campaigns occur, traffic can surge abruptly, causing system overload.
• DDoS Attacks (Distributed Denial of Service): These attacks aim to overload systems by sending a large volume of invalid requests from multiple sources, rendering the system unable to handle them and causing it to cease functioning.

Insufficient Resources for Handling Access

• Limited Resources: If the system is not allocated sufficient resources such as bandwidth, memory, CPU, it may lack the capacity to process high volumes of access, leading to downtime.
• Uneven Resource Distribution: In virtualized environments, when resources are not evenly distributed among servers or applications, situations may arise where some software consumes all resources, causing downtime for other applications.

Overload and inadequate essential resources can lead to critical downtime incidents. Resource management and accurate prediction of access volumes are crucial for maintaining stable performance and avoiding unexpected downtime.

3.3. Underlying Factors and Predictive Capability of Downtime

Precursors for the Occurrence of Downtime

• Abrupt Increase in Traffic: When there is an abnormal surge in the number of users or access traffic, this may serve as a precursor to impending downtime.
• Frequent Error Reporting: If the system logs frequent minor errors or warnings, this could be a predictive indicator of larger impending issues.
• Elevated Failure Rates in Request Processing: When the failure rate in request processing significantly rises without a clear explanation, this may indicate that the system is experiencing issues that could lead to downtime.

Obscure Factors That Can Cause Downtime

• Natural Elements: Natural factors such as storms, power outages, or earthquakes can unexpectedly cause downtime without prior prediction capability.
• User Error: Incorrect system usage or errors from users can also create downtime situations.
