IB current systems status can be monitored online here:?
I have logged in today and a few times tomorrow with no problem (though I usually do so with a direct account link from TWS to save the trouble of manually logging in).?
Admittedly IB has problems from time to time but nothing exceptionally serious in my experience since July 2019 when they botched their 2-factor authentication and couldn't get it back to work for quite a few days if memory serves me well.
