Between 16:37 and 16:55 CEST, we experienced an issue where 51.30% of all Mastercard 3DS requests failed across multiple issuers. Our investigation confirmed this was caused by an influx of improperly formatted error messages received directly from Mastercard.
The issue subsided at 16:55 CEST, and our monitoring confirms that 3DS authentication for Mastercard has remained fully stable since then.
