Or it's something about your own connection. Maybe an ad blocker? For me, the redirect works:

I got it specifically because they had a mini rant about the weight of switches that other vertical mice use, and while I couldn't tell if that was a real problem, that's the kind of mentality I used to ascribe to Logitech.
The MX4 is clearly marketing logic. The haptic feature adds nothing of note, and 100% feels like their marketing people got to preempt the core goal of making an ergonomic mouse so they could have a headline.

Then I realized that they have a galaxy of consultants and experts that effectively make a living by keeping on top of all issues and fixing them for a fee. So there is little incentive for them to actually be user-friendly: as long as they are "partner friendly" with timely material, that's good enough.
They are not alone in this, btw - pretty much all major platform providers do this, one way or the other.
A common solution is to create placeholders at the old URLs with permanent redirects to the new URLs, but that doesn't fix all of the old hyperlinks, so it becomes extremely expensive to maintain backwards compatibility after 2 or more CMS changes.
