For the last 12 hours users trying to make any payments via a credit
card would have received an error that the payment had failed.
After investigating this, we've found out what the problem was, and have
now fixed it. The nature of the problem was such that our system was
reporting the payments as failed, but they had actually gone through.
Because of that, what we've decided to do is:
- For standard "add to account pool" type payments, we'll refund any
duplicate payments, and complete the first payment so the money will
appear in the account pool
- For new account signups, if the account has a valid backup email
address, we'll refund any duplicate payments, allow the first
payment to complete, create the account, and email the backup
address to let the person know the account has been created
- For new account signups, if the account doesn't have a valid backup
email address, we'll refund all payments, and close the account as
if it never was created, because there's no way to inform the person
that was trying to signup
Because we use a "delayed capture" system for pyaments, this means for
the transactions being refunded, users should never even see the
transaction appear on their credit card statement.
