IB short list

Anyone have a problem with IB short list today. My TWS told me I couldn't short SNDK or XLNX.

 

yep brcm aapl

 

Yeah. XOM went from shortable, to not, and then back.
I checked, and it was on their shortable list.

 

IB had some type of problem yesterday am as well.
(yesterday = tuesday).

at 7:45 am (est), virtually the entire short list went bye bye. went from 5300 stocks available to 475 stocks available. it came back up at 845...

i notified them when it happened, and waited in chat- it came back up during that time.
