In practice it is a contract with a definition, a measurement method, an exclusion list, and a compensation formula \u2014 and the compensation is almost always service credit, not cash. This article walks through how to read a hosting SLA in ten minutes and calculate what an outage actually pays you, so you can tell a meaningful guarantee from a decorative one.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Uptime Percentages in Real Downtime<\/h2>\n\n\n\n<figure class=\"wp-block-table\"><table><thead><tr><th>Advertised uptime<\/th><th>Downtime per month<\/th><th>Downtime per year<\/th><\/tr><\/thead><tbody><tr><td>99.0%<\/td><td>7h 18m<\/td><td>3.65 days<\/td><\/tr><tr><td>99.5%<\/td><td>3h 39m<\/td><td>1.83 days<\/td><\/tr><tr><td>99.9%<\/td><td>43m 12s<\/td><td>8h 46m<\/td><\/tr><tr><td>99.95%<\/td><td>21m 36s<\/td><td>4h 23m<\/td><\/tr><tr><td>99.99%<\/td><td>4m 19s<\/td><td>52m 35s<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Note how narrow the spread is between 99.9% and 99.99% on a monthly basis \u2014 43 minutes versus 4. Only a handful of outages per year separate the two, which is why the credit payout matters more than the headline number.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">The Credit Formula Most Contracts Use<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Standard credit schedules are tiered on monthly uptime percentage:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>99.9% to 100% \u2014 no credit<\/li>\n<li>99.0% to 99.9% \u2014 10% of monthly fee<\/li>\n<li>95.0% to 99.0% \u2014 25% of monthly fee<\/li>\n<li>Below 95.0% \u2014 50\u2013100% of monthly fee<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Run the numbers. A $10\/month VPS with four hours of downtime in a month sits at roughly 99.4% \u2014 which lands in the 10% tier. Your compensation is <strong>$1.00<\/strong>. For a single-site hobby project that is fine. For anything revenue-generating, it is negligible compared to the cost of the outage.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Exclusions That Void Your Claim<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Scheduled maintenance<\/strong> \u2014 usually excluded, and notice periods can be as short as a few hours.<\/li>\n<li><strong>&#8220;Emergency&#8221; maintenance<\/strong> \u2014 broadly defined, frequently unannounced.<\/li>\n<li><strong>Network outside the provider&#8217;s control<\/strong> \u2014 upstream transit issues are typically excluded.<\/li>\n<li><strong>Client-side or application faults<\/strong> \u2014 including your own misconfiguration.<\/li>\n<li><strong>DNS and domain issues<\/strong> \u2014 rarely covered even when caused by the provider&#8217;s nameservers.<\/li>\n<li><strong>Force majeure<\/strong> \u2014 standard, and reasonable.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The exclusion list is where most claims die. Check it before you check the uptime number.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How Downtime Is Actually Measured<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Monthly vs annual window.<\/strong> Annual measurement lets a provider absorb a full bad month and still report compliance.<\/li>\n<li><strong>Single probe vs multi-region.<\/strong> One monitoring location is easily gamed or misreported.<\/li>\n<li><strong>ICMP ping vs service check.<\/strong> A host can respond to ping while your web service is down \u2014 ping-based SLA definitions are nearly worthless.<\/li>\n<li><strong>Provider-side monitoring.<\/strong> If the only measurement is the provider&#8217;s own dashboard, you have no independent evidence.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Before purchasing, run an external monitor. A free service checking HTTP every minute gives you a log that beats any dispute.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Claim Process: What to Expect<\/h2>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Document the outage: start time, end time, and independent probe evidence.<\/li>\n<li>Submit the credit request within the stated window \u2014 commonly 7 to 30 days after the incident. Miss this and you forfeit.<\/li>\n<li>Expect credits to be applied to a future invoice, not refunded.<\/li>\n<li>Expect the provider to investigate first; many claims are resolved only after a support escalation.<\/li>\n<li>Keep the ticket reference and the credit confirmation for your records.<\/li>\n<\/ol>\n\n\n\n<h2 class=\"wp-block-heading\">What Credits Do Not Cover<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Service credits compensate the hosting fee, never the business impact. Lost sales, SEO ranking dips from crawl errors, and customer churn are all outside scope. If your risk exposure exceeds a few hundred dollars per hour, an SLA credit is not your risk mitigation \u2014 redundancy is.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That is why the practical complement to any SLA is a second instance in a different region or on a different provider. The arithmetic is covered in <a href=\"https:\/\/affordablevpsserver.com\/when-to-add-a-second-vps-instead-of-upgrading\/\" rel=\"nofollow\">when to add a second VPS instead of upgrading<\/a>, and provider-level reliability differences are in the <a href=\"https:\/\/affordablevpsserver.com\/#providers\" rel=\"nofollow\">comparison table<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">A Ten-Minute SLA Checklist<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Is the uptime target measured monthly or annually?<\/li>\n<li>Is measurement internal, external, or self-reported?<\/li>\n<li>Does the definition cover service availability or just network reachability?<\/li>\n<li>What is the credit percentage at 99.0%, 95.0%, and below?<\/li>\n<li>How long is the claim window, and how must evidence be submitted?<\/li>\n<li>Are credits capped at the monthly fee?<\/li>\n<li>Which exclusions are broad enough to swallow most incidents?<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Choosing Providers on SLA Substance<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Providers that state a monthly measurement window, use external monitoring, and publish a clear credit schedule are the ones worth trusting. InterServer publishes standard service commitments and applies credits to the account without a lengthy dispute process, which keeps expectations simple for budget buyers.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/www.interserver.net\/vps?id=1067793\" rel=\"noreferrer noopener sponsored\" target=\"_blank\">View InterServer VPS plans and SLA terms \u2192<\/a><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Bottom Line<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">An SLA is a credit schedule, not an insurance policy. Read the measurement window, the exclusions, and the tier table; then compute the payout for a realistic outage on your plan. If the number is small \u2014 which it usually is on a $5\u2013$10 VPS \u2014 treat it as a minor goodwill gesture and invest in redundancy instead.<\/p>\n\n","protected":false},"excerpt":{"rendered":"<p>&#8220;99.9% uptime guarantee&#8221; sounds like a promise.
