Running Online Exams Without Crashes
Online assessments create sudden traffic spikes. Here is how to prepare infrastructure.
Online exams create intense, synchronised load: hundreds or thousands of students logging in at the same minute, loading questions and submitting answers at the same deadline. Systems that work fine on normal days can fail under this pressure.
Load test in advance
Simulate the expected number of students logging in and submitting simultaneously. Identify bottlenecks in servers, databases and networks.
Scale infrastructure
Increase server capacity for exam periods. Cloud hosting makes temporary scaling practical.
Stagger logins where possible
Opening login windows a few minutes before the exam spreads load.
Optimise the exam platform
Reduce heavy images, enable caching and ensure database queries are efficient.
Campus network readiness
For on-campus exams, verify Wi-Fi capacity in exam halls and labs, and use wired connections where possible.
Backup connectivity
Redundant internet links prevent a single fault from disrupting exams.
Protect against attacks
Exams can attract DDoS attacks or cheating attempts. Ensure DDoS protection and secure access controls.
Auto-save answers
Platforms that save answers regularly protect students from losing work during brief disruptions.
Contingency plans
Define what happens if systems fail: extended time, rescheduling or offline alternatives.
Support team
Have technical staff on standby during exams with clear escalation paths.
