On a Thursday afternoon in August I typed my own domain into my own browser and got an error. Not a slow page or a broken layout. The connection failed outright, and Chrome told me the site had an SSL protocol error.
I did what anyone who runs a website does. I assumed I had broken something. I checked the certificate. It looked fine, but a certificate is the usual suspect, so I renewed it anyway. That did nothing. I checked DNS, the host, and the deploy log. Everything was healthy. The site was up and serving normally to the rest of the world. It was broken only for me.
The cause had nothing to do with my site. My home internet provider is Spectrum, and Spectrum includes a service called Security Shield, which runs on a threat classification platform built by a company called CUJO AI. Somewhere inside that system, valsier.com had been classified as a suspicious site and blocked. The block matched on the hostname rather than the destination address. Requests on port 80 were redirected to a Charter-hosted block page. Requests on port 443 had the connection broken before the handshake finished, which is exactly what a certificate failure looks like from inside the browser.
So the error message I spent an afternoon chasing was not describing what had happened to my site. It was describing what the filter had done to the connection.
You might not expect what happens next. I sent Spectrum an unblock request that same afternoon. They answered the next day. The reply stated in writing that the site had been incorrectly blocked, that it was safe to visit, and that they would update their rating for it. One business day, in writing, with the error acknowledged. I have filed complaints that took three weeks to produce less. Spectrum handled this well and I am not going to pretend otherwise.
The problem is not the response. The problem is everything that had to happen before there was a response to give. Consider what the classification cost to make. It was automatic. No person reviewed it. It produced no notice to me, no email, no entry in any console I had access to, and no stated reason I could read. It applied at once to every subscriber on that network. Whatever it cost, it cost that once, and then it held.
Now consider what it cost to find. I had to be a customer of the specific provider that was blocking my site. Had I been on a different network, my site would have been unreachable to a large population of people and perfectly reachable to me, and I would have had no signal at all. I had to happen to look at my own site during the window. I had to keep going after the certificate theory collapsed, which cost an unnecessary renewal and most of an afternoon. And I had to land on an explanation that requires believing a third party made a mistake, rather than the far more ordinary explanation that I had broken my own deployment. For several hours I believed the ordinary explanation. And I was wrong.
The response was bounded at one day. The discovery was unbounded, and it ended only because of a coincidence.
Here is the number I would most like to give you and cannot. I do not know when the block started. I found it on August 13th. It could have begun that morning or three months earlier. There is no record I can request, no timestamp I can look up, and no notification sitting anywhere waiting for me. The duration of a decision made about me is not information I have access to.
Scale is part of the shape here. CUJO AI's platform runs on the networks of Comcast, Charter, Cox, Rogers, TELUS, Sky and others, and the company has described its reach in terms of tens of millions of households. I am not claiming my site was blocked across all of them. I have no way to test that. What I am pointing at is the structure. A classifier operating at that scale makes decisions about websites continuously, and the parties those decisions are about are not participants in them.
One further distinction, and I hold it as an open question rather than a finding. The reversal came from Spectrum, the distributor. It did not come from CUJO, the classifier that made the call. Whether CUJO's model was corrected or one entry was patched in one operator's list is not something I can determine from outside, and Spectrum's wording does not settle it. What I can report is what is publicly available. CUJO's site publishes no security.txt. Its vulnerability disclosure policy addresses software security vulnerabilities and does not mention misclassification. Its WHOIS record is redacted. The contact page offers a sales form. There is no published route by which the subject of a wrong classification reaches the company that classified them. That does not mean the company would refuse to help. It means the route is not there to find.
This column is usually about chatbots, and there is a reason I am writing about a network filter instead. Behavioral quality is a property of how an automated system treats a person, and a system does not have to speak to a person in order to treat them a particular way. Nothing here addressed me. Nothing here held a conversation with me. A decision was still made, it still had a consequence I carried, and the structure around it gave me no standing: no notice, no reason, no route, no record. The chatbot version of this is easier to see because the harm arrives in sentences. This is the same property with the interface removed.
Capability measurement would score this system on how accurately it classifies sites. Safety measurement would ask whether it lets harmful traffic through. Both are real questions and neither one asks what mattered to me, which is what the system owes the party it decided about.
I got a good outcome in one day because I happened to be a customer of the right company. That is not a process. That is luck, and the question worth sitting with is what happens to everyone who does not have any.
