Reminds me of when I worked at AT&T, on a team that was running a very small file transfer service internal to the corporate firewall. Literally a couple week project that you'd find in a tutorial.
We were asked to check in with the accessibility folks to make sure everything was good with our emails that we were sending. It was a completely plain-text email, so just about the most accessible you can get, so I didn't expect any issues. We had a QA person who was blind look it over informally and said it was great.
The accessibility people said we had to undergo a formal review, and they could do it in six to ten, nbd.
I asked what unit of six, like six weeks? No, six to ten months. And we would have to stop sending email in the interim, for sure, definitely not permitted.
After all, our emails didn't even have all the graphics and corporate branding (and features to make the graphics and corporate branding "accessible") that were required. No, there's no guidelines, the committee has to review it.
I informed them that the CTO of the company was using the file transfer service for sending out his weekly meeting slides. No more complaints were received, and I left the company well before their timeline rolled around for review.
Would be interesting to know if the service was still operating and sending plain text emails.
