BigTimeUp performs comprehensive monitoring of your websites every 5 minutes, tracking uptime, performance, and security.

Every 5 minutes, BigTimeUp's monitoring system performs automated checks of your websites. Here's what happens during each check:

Uptime monitoring checks whether your website is accessible and responding correctly. A site is considered "up" when:

• The server responds to the HTTP request
• The HTTP status code is in the 2xx or 3xx range (success or redirect)
• The response is received within the timeout period (30 seconds)

A site is marked as "down" when:

• The server doesn't respond (connection timeout)
• The HTTP status code indicates an error (4xx or 5xx)
• The server returns an invalid or corrupt response
• DNS resolution fails

Response time is the total time it takes for your website to respond to an HTTP request, measured in milliseconds. This includes:

• DNS Lookup: Time to resolve your domain name to an IP address
• Connection Time: Time to establish a TCP connection to your server
• SSL Handshake: Time to establish a secure HTTPS connection (if applicable)
• Server Processing: Time for your server to process the request and generate a response
• Transfer Time: Time to transfer the response data

BigTimeUp tracks three key response time metrics:

• Average Response Time: Mean response time across all successful checks
• Minimum Response Time: Fastest response recorded
• Maximum Response Time: Slowest response recorded

For HTTPS websites, BigTimeUp automatically monitors your SSL/TLS certificate to ensure it remains valid and doesn't expire unexpectedly.

We track:

• Certificate Validity: Whether the certificate is currently valid and trusted
• Expiration Date: When the certificate will expire
• Days Remaining: How many days until expiration
• Issuer: The Certificate Authority that issued the certificate

You'll receive an email alert 30 days before your SSL certificate expires, giving you plenty of time to renew it before users encounter security warnings.

BigTimeUp calculates uptime as a percentage based on successful checks versus total checks:

BigTimeUp retains detailed monitoring data for 30 days. This includes:

• Individual check results (up/down status)
• Response times for each check
• HTTP status codes
• Downtime incident records
• SSL certificate check history

After 30 days, detailed check data is aggregated into hourly summaries to maintain long-term trends while managing data storage efficiently.
