Service Level Agreement

Our Service Level Agreement: monthly uptime targets, support response times, how we measure, and the credits you receive automatically when we miss.

Last updated · 28 April 2026 · Version 1.0 · Tier: Production hosting · Target: 99.99% / month · Credits: automatic.

1. Scope

This Service Level Agreement (“SLA”) applies to all production hosting plans (Single, Atelier, Atlas) of Hosting by Ampersand. Staging environments and add-on services (Maintenance, Transfer) are best-effort and not covered by uptime credits.

2. Uptime commitment

Plan Monthly uptime Max downtime / mo
Single99.95%~22 min
Atelier99.99%~4 min
Atlas (dedicated)99.995%~2 min

3. Support response times

Severity Definition First response
P1 — DownSite or service is fully unavailable.≤ 30 minutes, 24/7
P2 — DegradedSevere performance regression or feature broken.≤ 2 hours, 24/7
P3 — IssueFunctional issue, no significant impact.≤ 4 business hours
P4 — QuestionHow-to, advice, account.≤ 1 business hour, Mon–Fri

4. How we measure

Uptime is measured from three independent external monitoring locations (Zürich, Frankfurt, Milan), at 30-second intervals, against the load balancer in front of your site. A minute is considered downtime if all three locations report failure for two consecutive checks. Per-customer monthly uptime is published on your dashboard.

5. Exclusions

The following do not count as downtime:

  • Scheduled maintenance announced at least 7 days in advance.
  • Issues caused by code, plugins, themes or content under the Customer's control (e.g. a fatal PHP error in a custom plugin).
  • DNS misconfiguration or domain expiry on the Customer's side.
  • Force majeure (natural disasters, cable cuts, large-scale internet routing failures).
  • DDoS attacks above 100 Gbps where we have already engaged upstream mitigation.
  • Service suspension due to non-payment or Acceptable Use violations.

6. Service credits

Credits are applied automatically when our internal monitoring confirms the breach. You don't have to ask. Credits cap at one month of fees per incident and are non-cashable.

7. How to claim

If you believe you experienced downtime that wasn't credited, email hello@ampersand.ch within 30 days of the incident with the affected URL and approximate time window. We'll cross-check our monitoring and respond within 5 business days.
