Business Web Hosting SLA Comparison

Bottom line

Do not compare SLA percentages alone. Compare covered services, exclusions, measurement periods, claim deadlines, and credit formulas.

Providers to review

iCLUSTA+, CPI, and XServer for WordPress publish different availability frameworks for different service scopes.

How to read an SLA

An SLA defines a service-credit process. It does not compensate every business loss and does not guarantee zero incidents.

Operational checks

Check web, mail, database, DNS, planned maintenance, status communication, and restore procedures.

Selection

Match the SLA to the actual business workload rather than selecting the highest headline percentage.

Coverage matters more than the headline

An SLA percentage is meaningful only with its covered services and measurement method. Determine whether web, mail, database, control panel, DNS, and additional domains are included. Planned maintenance, customer configuration, network routes outside the provider, and force-majeure events may be excluded.

A provider may advertise 100% while another advertises 99.99%, yet the lower percentage can cover a different technical scope. Read the service agreement rather than ranking providers by one number.

Credits and claims

Most hosting SLAs provide service credits or fee refunds, not compensation for lost sales, staff time, or reputational damage. Check the credit schedule, maximum refund, evidence requirements, claim deadline, and whether the customer must submit a request.

Maintain independent monitoring if availability is business-critical. Provider status records and customer monitoring may use different measurement points.

Continuity controls outside the SLA

Backups, tested restoration, DNS access, mail continuity, administrator credentials, and an incident contact tree reduce business impact more directly than a credit after the event.

Select a provider whose support and recovery procedures match the organization’s recovery-time and recovery-point objectives.

Procurement checklist

Before approval, obtain a written quotation or save the checkout summary. Record the plan, contract term, surcharge, domain registration and renewal, certificate options, migration assistance, restore fees, and cancellation procedure. Assign an owner for DNS, mail, CMS updates, backups, and incident communication.

Run a non-production test using the expected number of domains, mailboxes, databases, scheduled jobs, and administrator accounts. Measure migration time, confirm outbound and inbound mail, test a backup restoration, and document the rollback path before changing production DNS.

Security and governance

Provider controls do not replace customer governance. Use named administrator accounts, multifactor authentication where available, least-privilege access, current CMS components, external backups, and a documented offboarding process. Review logs and provider notices regularly.

For regulated or sensitive workloads, confirm data location, subprocessors, retention, access records, vulnerability handling, and contractual responsibilities with the provider. A shared hosting plan may be suitable for a public website but not for every application or data classification.

Ongoing review

Recheck pricing and specifications at renewal because surcharges, capacity, supported software, and campaign terms can change. Compare the actual annual invoice and support usage with the original estimate.

Track uptime, page performance, mail delivery, restore tests, support response, and administrator effort. These operating measurements provide a better renewal decision than marketing claims alone.
