Please be advised that a subset
of customers using BOE order entry sessions have been unable to login to EDGX
Options due to a login message decoding error related to a software update that
was applied last evening. Cboe is working on a corrective patch and will
restart impacted sessions to allow affected customers to connect as soon as
possible. Will advise once this issue has been resolved.
