Response Times and What a Website SLA Actually Means
Service level agreements are written to be reassuring. Read closely and you find that the numbers usually describe intentions, and the remedies usually amount to a partial credit. That does not make them worthless; it means you should know what you are buying.
Uptime percentages, translated
- 99% allows about 7 hours of downtime a month. That is a lot.
- 99.9% allows about 43 minutes a month. This is the common promise.
- 99.99% allows about 4 minutes a month, and is rare below enterprise pricing.
Then read the exclusions: scheduled maintenance, third-party failures, DNS problems, your own plugins, and attacks are usually excluded. What remains is narrower than the headline number.
Response time versus resolution time
Most agreements promise a first response, not a fix. "One-hour response" can mean an automated acknowledgment. Ask specifically: what is the typical time to resolution for a site that is down, and who decides priority? A provider who answers with real numbers has measured it; one who repeats the marketing line has not.
The questions worth asking
- Is support 24/7 for outages, or business hours only?
- Is there a phone number, or only tickets?
- Does support cover the application, or only the server?
- What counts as an emergency, in their words?
- What is the remedy when they miss, and is it automatic or do you have to claim it?
- Who is the escalation point, and how do you reach them?
What matters more than the document
Monitoring you control, so you learn about an outage from your own alerts rather than a customer. A recent, tested backup. Access to your own hosting account. And a documented path for the first fifteen minutes. Those four are worth more than any credit clause, because they shorten the outage instead of compensating for it.
A fair expectation
For a small business site, a good provider should acknowledge an outage quickly, work it continuously until resolved, and tell you what happened afterwards. Those three behaviors, consistently, matter more than the decimal places. Ours are written into our care plan terms for exactly that reason.
