Other broker-dealers restricted trading due to capacity issues. For example, one firm’s system created a unique ID for each order, but purportedly reached a limit in the number of unique IDs it was able to create on January 27, 2021. The following day, January 28, when the firm realized that it would likely run out of unique IDs again, it restricted customers from making new purchases of shares of GME and AMC and from opening option positions in these stocks during the last one and a half hours of the trading day. Customers were still permitted to close their existing long or short GME and AMC positions, and the restriction was lifted before the market opened on January 29.

Wow.
