That’s an entirely different type of problem, and avoidable by just using us-east-2 (I still don’t understand why people default to us-east-1 unless they require some highly specific services).
I remember a Workspaces outage about 5 or 6 years ago, and the problem for us was that the redirect link in the console had US East 1 in it.
The workspaces themselves weren't in US East 1 and nothing relied on US East 1.
Emailing users who needed it an alternative link with a different region in the URL for the login redirect fixed it for us.
