FAQ

CDN Performance Optimisation FAQ

Common questions before starting fixed-scope infrastructure, automation or support work.

Can you help with CDN Performance Optimisation?

Yes. We can review the issue, confirm the affected systems and provide fixed-scope support where the work fits our infrastructure, automation and server support services.

What details should we send?

Useful details include the affected system or service name, what changed before the issue appeared, relevant logs, errors or screenshots with secrets removed, plus the urgency and desired outcome.

Can you work on production systems?

Yes, but carefully. We confirm access, backups, risk and rollback options before making changes that could affect live services.

What happens after we contact you?

We review the details, confirm whether it is suitable for emergency support, fixed-scope work, a review or a larger project, then provide the next step.

How much does this work usually cost?

Fixed-scope work is quoted after we understand the issue, risk and access requirements.

After the fix

Reduce the chance of the same issue returning.

After a fixed-scope issue is resolved, we can also help with monitoring, backups, restore testing, security hardening or ongoing infrastructure support where it makes sense.
