1930 BST(+0100) – The search ability of the North American mail archive’s has been restored and the archive search will now be returning results.
There will be delays in indexing of messages submitted to the archive since 1st September meaning that these will not be immediately searchable in the message archive although they have been successfully stored. We have initiated the re-indexing of the messages so these will become available once the indexing is complete.
This issue has been caused by a configuration database cluster issue, at no point has there been any risk to message storage. Our engineering teams are further investigating the cause of the issue, and putting further systems in place to ensure that this does not recur.
