On-call support and emergency incident response
Outages and critical vulnerabilities do not wait for business hours. WITSB provides scheduled on-call coverage for teams that need a backup engineer, and emergency help when something is already broken.
What we cover
- Linux and Windows servers, web servers and databases
- MFT and SFTP platforms during critical transfer windows
- Cloud infrastructure, containers and CI/CD pipelines
- WordPress and LAMP hosting stacks
Emergency incident response
- Triage, stabilization and service restoration
- Urgent patching for newly disclosed vulnerabilities, with backups and a rollback plan
- Recovery from failed upgrades, full disks, expired certificates and broken deployments
- A written summary of what happened, what was changed and what to fix next
On-call retainers
Coverage windows, escalation paths, response targets and access are agreed in writing before the retainer starts, along with runbooks for your most likely incidents.
Questions
Can you help with an outage that is happening right now?
Call or email with what is down and how we can reach the system. Emergency work is billed hourly and starts once access and scope are confirmed.
How does on-call coverage work?
We agree on hours, systems, escalation contacts and response targets, gain secure access ahead of time, and prepare runbooks so incidents are handled quickly and consistently.
