Both Fidelity and Schwab were fine for me on devices where I was already logged in, but logging into a new device wasn’t working.

This seems like a common issue - even if backend systems can take the load, login systems all seem to have a lower TPS limit and have a lot of trouble during big surge events like this. It reminds me a lot of when a new video game releases where the issue is often the login servers being overloaded.

I can't login on a device i always use, so the failure is more complex than your sample

I’m not sure how the inability to login is “more complex”. I clearly state in my comment that logging in wasn’t working.

Revalidating session data could be a smaller surface area than validating a fresh login. But if logging in existing devices works in some cases, and doesn't in others, the failure case is more complex than just fresh logins don't work.

Ah, yes, my original comment was a little unclear. I actually wasn’t logging in on new device vs existing device, it was that I had logged in to one device before 9:30est (presumably before the surge began) and just had an existing already-logged-in-session.

Maybe logins are being throttled deliberately, to protect the transaction servers -- to which all institutional clients are already logged in.

West Coast retail customers are out of luck.
