Uptime monitoring that catches downtime before customers do
Checked from multiple global locations, with up to 4 retries and exponential backoff before any alert fires. Choose a check interval from 30 seconds to 24 hours, depending on your plan.
A rolling SLA you can actually report
WebPixie tracks uptime over time and rolls it into an SLA figure, with the incident count and response trend behind it, so you have a number to share instead of a guess.

The SLA is calculated on an industry-standard basis that excludes periods when monitoring was paused, so the figure reflects real availability.
Checked from multiple global locations
Every interval runs from each location, so a slow or unreachable region surfaces on its own instead of hiding behind a healthy one.
Enterprise can add more locations as needed.
Each check validates more than a 200
Set the HTTP method, headers, expected status code, a body keyword, and authentication, so a check confirms the page is actually working, not just reachable.
Four retries before we wake you
A network failure has to survive four backoff retries before an incident opens, so a momentary flicker on one route does not page you at 3am.
Retries apply to network failures such as timeouts and connection errors. A non-matching status code or keyword opens an incident on the first check.
How WebPixie watches your uptime
WebPixie runs uptime checks from multiple global locations on a schedule and alerts you when a check confirms a failure. There is no agent to install, no DNS changes, and no server access needed. Every check verifies the HTTP response code, response time, SSL validity, and any custom keyword you configure. Over time you get uptime statistics, SLA reports that exclude unmonitored periods, and 30-day trends, so you can measure reliability and track mean time to recovery.
Network-related failures, like timeouts or connection errors, get up to 4 retries with exponential backoff before WebPixie opens an incident, so a momentary flicker on one route does not wake you at 3am. When a failure is confirmed, alerts route through email, Slack, or webhook depending on your plan.
The checks run from multiple global locations, including London, Istanbul, and New York. A problem in one region does not blind the others, which keep checking that your site is reachable.
Stop refreshing the homepage to check if it is working
Automated checks tell you what manual refreshing cannot
Most downtime starts predictably: a deploy goes wrong, a memory leak builds, a DNS record changes. WebPixie lets you set a check interval from 30 seconds to 24 hours depending on your plan, so high-priority monitors run often and low-priority ones run sparingly. When a check fails, an alert routes to your preferred channel.
Receive smart alerts, not 3am false alarms
Retry logic with exponential backoff before any alert fires
A network-related failure, like a timeout or connection error, retries up to 4 times with exponential backoff before WebPixie opens an incident, so a momentary flicker does not wake you. Alerts route through email on every plan, Slack on Starter and above, and webhooks on Pro and above.
Check from multiple global locations
A regional outage hits one path, not the others
A site can look fine from one location while being unreachable from another. WebPixie checks from multiple global locations, such as London, Istanbul, and New York, so a regional reachability problem surfaces instead of staying hidden. Enterprise can add more locations as needed.
What uptime monitoring checks, and what it does not
HTTP availability vs the rest of the WebPixie suite
Uptime monitoring checks HTTP and HTTPS reachability using the HTTP method, headers, expected status code, and authentication you configure, plus response times and a body keyword that confirms the page is functioning correctly, not just returning a 200. An expired SSL certificate or lapsed domain will make the HTTPS check fail, so uptime sees it once the site is already down. What it cannot do is warn you ahead of expiry, or surface a changed DNS record or a broken link on a deeper page before it causes an outage. Those have their own monitors that catch the cause early, and all 5 monitor types are included on every plan.

Why teams choose WebPixie for uptime
Up to four retries before we wake you
Exponential backoff between retries means a flaky CDN edge or a routing flicker will not open an incident.
Multiple locations, independent network paths
Checks run from multiple independent locations, such as London, Istanbul, and New York, so a regional outage hits one path, not the others.
Check intervals from 30 seconds to 24 hours
Pick the interval each monitor needs, from 30 seconds to 24 hours, with the fastest intervals available on higher plans.
Frequently Asked Questions
Common questions about uptime monitoring.
Website monitoring is the practice of automatically checking whether a website is reachable, responding well, and returning expected results. Monitoring services like WebPixie check your site from multiple global locations, verify HTTP response codes, check SSL certificate validity, watch for DNS record changes, and crawl your pages in depth. When something goes wrong, the service sends alerts through your chosen channel so you can respond without waiting for a user report.
There are several types of website monitoring, each catching a different class of issue:
- Uptime monitoring: Is the site or service reachable?
- SSL monitoring: Is the certificate valid and not about to expire?
- DNS monitoring: Are there configuration problems?
- Domain monitoring: Is the registration about to lapse?
- Link Crawler: Are internal and external links accessible?
Most teams need all of them. That's exactly why WebPixie brings them together on a single platform.
WebPixie sends alerts within seconds of detecting an issue. The exact time-to-alert depends on your check interval. On the Pro plan with 60-second checks, you know about an outage within 60 to 90 seconds of it starting. On Enterprise with 30-second checks, within 30 to 60 seconds. On the free plan with 15-minute checks, the worst-case detection window is 15 minutes.
To prevent false-positive noise, WebPixie retries failures caused by network problems such as timeouts or connection errors up to 4 times with exponential backoff before opening an incident. This helps confirm a real outage versus a flaky network, so you don't get woken at 3am for a routing flicker in one region.
Alerts route through email (every plan), Slack (Starter and above), and webhooks (Pro and above). Webhooks integrate with PagerDuty, Opsgenie, or any incident management tool you already use. For SMS or voice escalation, route the webhook through a service like PagerDuty.
Monitoring intervals are plan-based, with current minimums set as: Free (15 minutes), Starter (5 minutes), Pro (1 minute), Enterprise (30 seconds). You can also configure longer intervals up to 24 hours for lower-priority monitors, so a critical API health endpoint can run more often than a low-risk marketing page. In uptime monitoring, the interval affects how quickly WebPixie can detect a failure before retry logic confirms the issue and opens an incident. Faster intervals are useful for customer-facing applications, checkout flows, authentication services, and status endpoints where even short downtime matters. Slower intervals may be enough for informational pages or non-critical internal tools. Check intervals, uptime check limits, and monitoring locations vary by tier, so compare the details on the pricing page. Confirmed failures can then flow into incident management and your configured notification channels.
WebPixie marks a site as down when an uptime check fails the response rules configured for that monitor. A failure can come from a timeout, connection error, unexpected HTTP status code, missing body keyword, or another expected condition that does not match. Uptime monitoring supports custom HTTP methods, headers, expected status codes, authentication, and keyword validation, so “down” can mean more than a simple 500 error. For network-related failures such as timeouts or connection errors, WebPixie retries the failed check up to 4 times with exponential backoff before opening an incident, which reduces false positives. Failures from deterministic conditions, such as an unexpected status code or a missing keyword, are confirmed without extra retries. If the issue is confirmed, WebPixie creates or updates an incident and sends notifications through the channels available on your plan. Check intervals and location limits are plan-based, and you can compare them on the pricing page.
WebPixie runs uptime checks from multiple monitoring locations, including London, Istanbul, and New York. These locations help verify whether your website is reachable from more than one network path, which is useful when a problem affects only a specific region, provider, or route. Each uptime monitoring check can validate response status, response time, expected content, and other configured conditions before an incident is created. The number of monitoring locations you can use depends on your plan, so compare location limits on the pricing page. Multi-location checks are especially useful for customer-facing sites, agencies managing client domains, and teams that need clearer evidence before escalating an outage. For Enterprise location requirements, contact us to discuss coverage.
WebPixie calculates uptime as the share of monitored time your site responded successfully, using the industry-standard method that excludes periods when monitoring was not active. The basic formula is successful (up) time divided by total monitored time, multiplied by 100 (Uptime % = Up time ÷ Total monitored time × 100). Uptime monitoring checks your site at your plan's interval from multiple monitoring locations, such as London, Istanbul, and New York, and records each check as up or down. Time before a monitor was created, or while it was paused, is left out of the total rather than counted as downtime, so the percentage reflects only what WebPixie actually observed. A single failed check does not immediately reduce your score either, because network-related failures such as timeouts or connection errors are retried up to 4 times with exponential backoff before the time is counted as down, which keeps a brief routing flicker from distorting the figure. The resulting percentage is what you compare against an SLA target, where the allowed downtime is the error budget the target permits. To translate a target like 99.9% into plain minutes for a day, week, month, or year, use the free uptime calculator. Check intervals and data retention depend on your plan, which you can compare on the pricing page.
