The Great Redirect Loop Disaster: A Post-Mortem From the Day Our SSL Config Ate Itself

Picture this: it's Tuesday morning, and your website is doing what websites do best - existing on the internet. Then, without warning, it becomes a digital ouroboros - a snake eating its own tail while users watch their browsers cry. Your HTTP traffic gets redirected to HTTPS, which gets redirected back to HTTP, which gets redirected back to HTTPS, in an infinite loop that would make Dante's Inferno look like a inspirational TED talk. This is the story of how that happened, and why your redirect configuration is probably one software update away from doing the same thing.

Tuesday, 6:47 AM - "Why Are People Calling?"

One major e-commerce platform woke up to the kind of Monday - except it was Tuesday - that makes infrastructure teams reconsider their life choices. Reports started flooding in: customers couldn't load product pages. Not "slow load." Not "occasionally broken." Just stuck. Loading spinner. Forever. The kind of broken where your website becomes a motivational poster about patience.

By 6:52 AM, monitoring alerts were screaming like a smoke detector at 3 AM. HTTP error 310 (too many redirects) had gone from a rounding error to the most popular status code on the site. Industry data shows that redirect loops typically cause 23-30% immediate traffic loss within the first 15 minutes, and this was tracking right on schedule. The support team's tickets weren't just piling up - they were achieving sentience and forming their own union.

The timeline matters here because this is where most teams start guessing. And guessing is how you end up rebooting prod at 7:00 AM while sweating through your third coffee.

7:15 AM - "Let's Trace This Thing Before We Break Something Else"

Credit where it's due: the incident response was methodical. Using browser developer tools and network analysis (or in SCOUTb2's case, automated redirect chain scanning), they traced the actual redirect sequence. Here's what happened:

1. User hits http://example.com
2. Apache/.htaccess forces redirect to https://example.com
3. Nginx reverse proxy (sitting in front) sees HTTPS traffic and redirects it back to HTTP because its configuration file was never updated
4. Repeat until browser gives up, throws a 310 error, and contemplates better career choices

This is the web development equivalent of two people apologizing in a doorway forever. "After you." "No, after you." Eventually, someone needs to walk backward.

The root cause? A seemingly harmless infrastructure update had added an Nginx layer to handle load balancing, but nobody - and let's be clear, nobody - updated the SSL/TLS configuration to match. The handoff between systems created a redirect loop so elegant in its stupidity that it could be framed as modern art.

7:45 AM - The Fix (And Why It Was Embarrassingly Simple)

Once they identified the culprit, remediation took roughly 12 minutes. A single Nginx configuration file got one line changed:

From: redirect all HTTPS back to HTTP
To: actually just pass it through to the backend already

Traffic came back. Loading spinners stopped spinning. Support tickets began their slow descent from "active crisis" to "normal Tuesday chaos." By 8:15 AM, the incident was officially resolved. But the post-mortem? That's where things got interesting.

The company implemented three changes: (1) automated redirect chain testing in their CI/CD pipeline, (2) mandatory SSL/TLS configuration audits whenever infrastructure changes, and (3) a shared documentation system so whoever handles load balancing knows what SSL certificate handling looks like. Revolutionary stuff. Also known as "basic process," but apparently novelty when you're in crisis mode.

Why This Matters to Your Site

HTTP-to-HTTPS redirect loops affect something like 8-12% of websites at any given moment, according to published crawl data. Most never notice because the loops are small and slow. Until they're not. Until they're catastrophic. Your site might have a redirect loop hiding right now, waiting for your next deployment to wake up and destroy everything.

Here's the genuinely useful part: if you haven't audited your redirect chains recently, do it today. Check your .htaccess, your Nginx config, your load balancer settings, and your CDN rules. Make sure they're all pointing in the same direction (spoiler: toward HTTPS). If you're using SCOUTb2 or any redirect analyzer, run a scan on your production domain right now. Don't wait for the 7:00 AM call from your CEO.

The irony of this whole incident? The company wanted to force HTTPS. They just wanted to do it exactly once, not infinitely.
