Arcot monitoring had detected an elevated rate of challenge transaction failures at 06:54 GMT. Arcot internal teams were able to take necessary actions to restore challenge transaction health at 07:36 GMT and with this update we confirm that the incident stands resolved.
Impact: Transactions that do not require a challenge step (frictionless) will not be impacted. The cardholder may experience increased latency while being challenged causing the cardholder to abandon the purchase or an error in the challenge window will be presented. If 'Attempts' processing is not available for this transaction, it is likely that the cardholder may be have been prompted for another payment method.
