FAQs
- Which tech calculator should I start with?
- Start with the decision you are making. Use the uptime SLA calculator for availability promises and downtime budgets, the streaming bandwidth calculator for concurrent video load, and the download or upload time calculators when you need to estimate how long a file transfer will actually take.
- Are these provider-specific or contract-accurate calculators?
- Not by default. These tools are built for planning and comparison, not for interpreting a vendor's exact contract language or billing rules. If a route references a platform or provider, verify the details with the current official documentation before making a commitment.
- Do you show the assumptions and formulas?
- Yes. We aim to make the math inspectable so you can see what the tool assumes, how the number is produced, and when you should sanity-check the result against your own environment or source material.
