Description:
A subset of users within the EU and Americas regions may have encountered a TLS certificate pop-up while using Workspace Apps.
Steps to reproduce:
Impacted users may have encountered a popup where "lh3.googleusercontent.com" is asking for a TLS certificate when using any Workspace Apps.
This issue does not impact any critical functions on the corresponding Apps, as an option to bypass the prompt is available to users.
Workaround:
The issue is mitigated now.

The issue with Workspace Apps has been resolved for all affected users within the EU and Americas regions as of Tuesday, 2026-06-16 19:41 PDT
From a preliminary analysis, the issue was due to a configuration error that inadvertently requested client certificates. Our engineers have mitigated the issue by fully rolling back the affected configurations to a previous working state.
We thank you for your patience while we worked on resolving the issue.
Have you been to San Francisco or the Silicon Valley?
It has been my experience in tech companies and social circles that the term nerd is often considered a badge of honor and is even used to refer to one's self and friends.
Except that qwerty_asdf wasn't referring to a /24 subnet, (s)he was talking about one of the three address spaces defined in RFC 1918 and described thusly:
"Note that (in pre-CIDR notation) the first block is nothing but a single class A network number, while the second block is a set of 16 contiguous class B network numbers, and third block is a set of 256 contiguous class C network numbers."
So it is common for crusty old network engineers and sysadmins to refer to 192.168/16 as "the class C" private block, even when they understand that you can subnet it however you'd like.
> ... (s)he was talking about one of the three address spaces defined ...
Right, I realized that when s/he said "reserved Class C range". It was more of a general observation. I always forget I have to be extremely specific here on HN.
