Your real cost per hour of downtime

Per minute

Per day

Per year (1% downtime)

This is your direct revenue loss. Doesn't include support overhead, customer churn long-tail, or developer panic-fix costs.

🛡 What protects against this?

Most downtime isn't a server crash — it's silent breakage: 200 OK responses with empty pages, language drift, broken checkouts, SSL expiry caught too late.

GuardLabs Care audits every URL on your sitemap every 30 minutes. When something breaks — you get alerted immediately, not when a customer complains.

How is the cost calculated?

Hourly cost = (monthly visitors / 720 hours) × conversion_rate × AOV × reputation_multiplier

Direct revenue loss: visitors during downtime × conversion rate × AOV
Reputation multiplier: accounts for delayed effects (churn, bad reviews, customer support load)
Excludes: server / dev panic costs, regulatory fines, lost SEO equity (often the largest hidden cost)

This calc under-estimates real cost. The numbers it shows are the minimum floor.
