"At around 07:00 BST on Friday morning, our transaction database began to
malfunction. Naturally, we followed procedure and switched to a backup
server. Unfortunately, the backup server began to drastically slow down and
was struggling to process live transactions.

Friday and the backup server could not handle such a large increase in
volume."
