How to Monitor Your Shopify Store Uptime with Vigilmon

Shopify handles the core infrastructure, but there's still plenty that can go wrong with your store that Shopify's own status page won't tell you about: your custom theme breaking, your storefront API endpoints failing, your custom domain misconfiguring, or your checkout integration going silent.

Here's how to set up practical uptime monitoring for a Shopify store.

What Shopify Does and Doesn't Monitor for You

Shopify monitors (and publishes on status.shopify.com):

  • Core checkout functionality
  • Admin panel availability
  • Shopify's CDN and core APIs

Shopify doesn't monitor:

  • Your custom domain (yourstore.com) resolving correctly
  • Your custom theme rendering without JavaScript errors
  • Your third-party app integrations (Klaviyo, Recharge, etc.)
  • Your custom Storefront API calls
  • Your SSL certificate on your custom domain
  • Your headless Shopify frontend (if you're using Hydrogen or a separate framework)

The Three Things Most Likely to Break on Your Shopify Store

1. Your Custom Domain

If your DNS settings drift (not uncommon after domain transfers or registrar changes), your custom domain can stop pointing to Shopify. Your store is still live at yourstore.myshopify.com but everyone visiting yourstore.com gets an error.

Monitor: Check https://yourstore.com from outside your network.

2. Your SSL Certificate on the Custom Domain

Shopify provisions and auto-renews SSL for your custom domain. But the renewal can fail, especially after DNS changes.

Monitor: SSL expiry check on yourstore.com.

3. Your Headless / Hydrogen Frontend (If Applicable)

If you're running Shopify Hydrogen (React/Remix-based) or a custom headless frontend on Vercel, Netlify, or your own server, that frontend can go down independently of Shopify.

Monitor: Your frontend deployment URL separately from your Shopify domain.

Setting Up Monitors in Vigilmon

Sign up at vigilmon.online (free tier covers 5 monitors).

Monitor 1: Storefront Availability

  • URL: https://yourstore.com
  • Type: HTTP
  • Expected status: 200
  • Interval: 5 minutes (free) or 1 minute (paid)
  • Alert: Immediately on failure

This catches your custom domain breaking even if Shopify itself is fine.

Monitor 2: SSL Certificate

  • Type: SSL expiry
  • Domain: yourstore.com
  • Alert threshold: 14 days before expiry

Shopify auto-renews, but you want to know if the renewal fails before it affects customers.

Monitor 3: Checkout Page

If your checkout is critical (it always is), monitor it directly:

  • URL: https://yourstore.com/checkout or https://yourstore.com/cart
  • Expected status: 200 or redirect (301/302 to login is fine)

Monitor 4: Critical Collection/Product Pages

Your best-converting collection or product page:

  • URL: https://yourstore.com/collections/your-main-collection
  • Expected status: 200
  • Response time alert: > 3 seconds (slow pages lose sales)

Monitor 5: Headless Frontend (If Applicable)

If you run Hydrogen or a custom React frontend:

  • URL: https://yourstore.com (or your frontend subdomain)
  • Keyword check: A string that appears on your homepage (to catch broken renders that still return 200)

Why Multi-Region Monitoring Matters for E-Commerce

A single-region uptime monitor checking from Frankfurt might not catch a CDN edge node failure that's affecting your US East Coast customers.

Vigilmon checks from multiple geographic regions and only alerts when multiple regions agree on the failure. For an e-commerce store, this means:

  • You don't get paged at 3am for a regional network blip
  • You do get alerted when real downtime affects a meaningful portion of your customers

Setting Up a Status Page

Vigilmon lets you create a status page at status.yourstore.com. This gives your customers somewhere to check during outages rather than flooding your support inbox.

Steps:

  1. Go to Vigilmon Dashboard > Status Pages
  2. Name it "Yourstore Status"
  3. Add your storefront and checkout monitors
  4. Point status.yourstore.com CNAME to Vigilmon's status page endpoint

What This Doesn't Cover

This guide covers availability monitoring. It does not cover:

  • Conversion rate drops (use Google Analytics 4 or Shopify's own analytics)
  • JavaScript errors in your theme (use Sentry or LogRocket)
  • Third-party app outages (Klaviyo, Recharge, etc. — check their status pages)
  • Inventory or fulfillment issues (Shopify admin)

For a Shopify store, uptime monitoring is the baseline. Layer conversion analytics and error tracking on top.
