- Uptime SLA
- A contractual commitment by the hosting provider to keep the client's website accessible for a defined percentage of time per month — commonly 99.9%, which allows roughly 43 minutes of downtime per month.
- Bandwidth
- The volume of data transferred between the server and visitors per billing period; exceeding the contracted limit can trigger overage charges or throttling.
- Acceptable Use Policy (AUP)
- A set of rules prohibiting specific content or activities on hosted servers — such as spam, illegal content, or resource-intensive processes — that protect other users and the provider's infrastructure.
- Shared Hosting
- A hosting arrangement in which multiple clients' websites reside on the same physical server, sharing its CPU, memory, and storage resources.
- Dedicated Server
- A hosting arrangement in which the client leases an entire physical server exclusively, providing maximum performance and isolation from other clients.
- DNS (Domain Name System)
- The system that translates a human-readable domain name (e.g., example.com) into the IP address of the server hosting the website.
- SSL/TLS Certificate
- A digital certificate that encrypts data in transit between the server and visitors' browsers, indicated by HTTPS in the URL.
- Data Backup
- Copies of website files and databases stored separately from the live server so they can be restored after data loss, corruption, or a security incident.
- Force Majeure
- A contract clause that excuses a party from performance obligations when failure results from events outside their control — such as natural disasters, power grid failures, or government actions.
- Service Credits
- Partial refunds or billing credits issued to a client when the provider fails to meet its uptime SLA, typically expressed as a percentage of the monthly fee per hour of excess downtime.
- Indemnification
- A clause requiring one party to compensate the other for losses, damages, or legal costs arising from specified events — such as the client's content infringing a third-party copyright.
- Termination for Cause
- The right to end the contract immediately and without penalty when the other party materially breaches its obligations — such as non-payment or AUP violations.
