** Update: As of 2:03pm Thursday 9th December, both SagePay and Mastercard report that this issue should now be resolved.
Mastercard SecureCode failures
Mastercard is currently experiencing some technical issues.
It’s possible that because of these, some of your customers may find it difficult to use Mastercard SecureCode to complete their
payment. As such, you may want to suggest that they use an alternative such as Visa or American Express.
We'll continue to post updates on our monitor page (www.sagepay.com/system_monitor), as we find out more. Please note you will need to sign into the Sage Pay website to access the monitor page.
