What this page is171,948 rows held · newest sealed read 2026-09-14

  • On 14 Sep 2026, 38 of the 276 companies answered 200 for at least one file they do not have, 152 answers in total.
  • drmartens.com, grainger.com, ninjakitchen.com, puma.com and sharkclean.com answered 200 for all seven addresses on that read, and one of them handed back byte-for-byte the same page for all seven.
  • Across the whole window that has happened 13,633 times in 171,948 sealed reads. A count built on status codes alone would carry every one of them.
  • We tell them apart by the body, not the status. Anything whose first character is a tag is markup, not a document — which is also how arcteryx.com is caught, since its /.well-known/ucp opens with <?xml version= and then a whole web page rather than the usual doctype.

Real rows out of our sealed copies

These are rows we read out of dated copies we keep ourselves. The live source shows today only, so once a row moves, what it said before is gone from the place you would go to look.

What this page cannot tell you

  • This page is about what a server did on one day, not about the company. A shop that answers 200 for a file it does not have is running an ordinary catch-all page, which is a normal way to build a website.
  • We keep the first 256 kilobytes of a body. A page longer than that is cut off and flagged, and the cut copy is still enough to tell a web page from a text file.
  • On 14 Sep 2026 we could not read one or more files at 83 of the 276 companies, because the server refused us, rate-limited us, timed out, or its robots.txt told us not to fetch. Those are shown as cannot tell. We never count a refusal as the file being gone.
  • The panel is a fixed list of 276 company websites, frozen before collection started. A company that is not on that list is not missing from this feed — we have never asked it anything. Email operations@ustechautomations.com with the companies you follow and we will tell you which of them we already hold.
  • This is the newest read only. A server that answered 200 with a page today may answer 404 tomorrow; we hold both answers, dated.
  • There are 7 days in the window with no read at all: 19 Jun 2026, 4 Jul 2026, 15 Jul 2026, 8 Aug 2026, 18 Aug 2026, 19 Aug 2026, 20 Aug 2026. Where a file appeared across one of those gaps we give the two dates we actually hold, never a guessed one in between.

See the file before you pay

You do not have to take our word for what is in the file. Here are 16 rows of the real thing, carrying all 8 of its columns, cut out of the dated copies we sealed ourselves. Nothing in it is made up and nothing in it is tidied up.

  • Open the 16 rows as a CSVA plain spreadsheet file. It saves to your machine rather than painting itself into a browser tab, and it opens in Excel, Numbers or Google Sheets.
  • The same 16 rows as JSONThe same rows again, laid out for reading with code.

What arrives after you pay: the buyer receives the whole file as a CSV — the same plain spreadsheet as the sample file above, not a login and not a web page —.

What you would be paying for: $59 a month, billed monthly, for the shops you name. Cancel any month by email, with no account to close and no notice period. We tell you which of the shops you name are on our frozen list, and which we cannot read at all, before you pay anything. After you pay, a person emails you the storefront-file changes as a CSV within one working day. How often a new one follows is agreed in that same thread.

These 16 rows are a slice of the file, not the whole of it. What we cannot show you here is how far back it goes: that is the part you are paying for.
