The move comes after exceptionally high user activity combined with a large-scale cyberattack that temporarily affected portal performance. According to updates shared regarding system operations, the board has now optimized the platform to provide students with a smoother and more reliable experience.

The revised system is intended to support students of Classes 10 and 12 applying for post-result services including verification of marks, obtaining scanned answer sheets, and re-evaluation requests.

CBSE Increases Portal Session Time to Reduce Application Interruptions

To improve usability and reduce stress among applicants, CBSE has expanded the duration students remain logged into the portal.

The adjustment was introduced after students reported difficulties caused by:

• Session expiration during form completion

• Automatic logout issues

• Interrupted submissions

• Delays while entering identification details

• Difficulty reviewing answer-sheet information

By extending session validity, students now receive additional time to:

• Verify personal information

• Complete Aadhaar and identity-related entries where applicable

• Review answer-sheet details

• Submit requests without repeated login attempts

• Report evaluation-related discrepancies

The board expects this change to improve overall accessibility and reduce application errors.

Heavy Traffic and DDoS Attack Created Initial Disruptions

During the first day of operations, the portal experienced exceptionally high traffic.

Reported platform activity included:

• Approximately 14,000 concurrent users

• More than 28,000 successful submissions within a few hours

At the same time, the portal reportedly faced a Distributed Denial of Service (DDoS) attack, with nearly 1.5 million malicious requests generated within two minutes.

The combination of legitimate user traffic and cyber interference led to temporary performance issues across the portal.

Students encountered problems such as:

• “Login Request Expired” notifications

• “Verification Failed” errors

• Session timeout interruptions

• Blank or frozen screens

• Distorted interface display on mobile devices

• Text overlap and navigation issues

CBSE subsequently implemented backend optimizations to stabilize access and reduce repeated submissions caused by interrupted sessions.

Security Infrastructure Strengthened with Expert Support

To protect the integrity of the post-result process, additional safeguards were introduced.

According to the update, the portal enhancement initiative was supported by a dedicated technical and security team involving:

• Government cybersecurity personnel

• Technical experts

• Academic specialists associated with premier institutions including IIT Madras and IIT Kanpur

The strengthened framework aims to ensure:

• Better protection against malicious traffic

• Stable student access

• Improved data security

• Reliable application processing

What Issues Can Students Report Through the Updated Portal?

Students who have already received scanned copies of their digitally evaluated answer sheets can use the portal to highlight discrepancies related to the On-Screen Marking (OSM)evaluation process.

1. Missing Pages or Missing Content

Students may report cases where:

• Pages appear completely blank

• Page numbering is incomplete

• Supplementary sheets are absent

• Graph sheets are missing

2. Unreadable Digital Answer Sheets

Candidates can raise concerns if:

• Uploaded answer scripts appear excessively blurred

• Handwriting cannot be read properly

• Digital copies affect answer verification

3. Errors in Evaluation

Students may also report situations such as:

• Answers left unchecked

• Marks not awarded for attempted responses

• Evaluation conducted using an incorrect question paper series

• Obvious inconsistencies in assessment

How the Updated Portal Benefits Students

The revised infrastructure is expected to make post-result services more student-friendly by offering:

• Longer session duration

• Reduced login failures

• Better mobile accessibility

• Enhanced cybersecurity protection

• More reliable rechecking and re-evaluation submissions

CBSE’s latest changes are intended to ensure that students can complete post-result formalities with greater confidence and fewer technical interruptions.

Key Highlights

• CBSE increased portal session duration after student feedback.

• Heavy traffic and cyberattacks affected portal performance initially.

• Over 14,000 concurrent users accessed the platform.

• More than 28,000 applications were processed.

• Security upgrades were implemented with expert support.

• Students can now report answer-sheet and evaluation discrepancies more efficiently.
