Free IT support tools and resources
TechSupport Team publishes practical resources for support engineers and the teams that hire them. Use the tools to define support levels, plan incident handoffs and check availability targets. All downloads are free and do not need an email address.
Summary
Start with the support-level handbook to define who owns each type of work. Use the severity template to classify impact, then the escalation matrix to name the next owner. The SLA calculator checks downtime budgets and vendor credit estimates. The conference index helps you plan training and events. These examples do not replace your support agreement.
Choose a resource for your task
Each resource includes an explanation, source links and a reusable tool or download.
L1, L2 and L3 support levels
Define L0 to L4 support levels, distinguish diagnosis from code changes, and download a support-level definition template.
SLA and uptime calculator
Convert uptime to allowed downtime, compare composite availability and estimate cloud service credits. Share a calculation without sending data to a server.
Escalation matrix template
Download an Excel workbook or CSV. Set roles, contact routes and time triggers using a clearly marked SaaS example.
Incident severity levels
Use SEV0 to SEV4 definitions and impact-versus-urgency matrices. Adapt the downloadable severity model to your own service.
Conference Index 2027
Compare IT, SRE, DevOps and ITSM events by published criteria. Download the data and add confirmed dates to your calendar.
