Emails sent from University accounts to a range of BT email addresses are being heavily delayed.
Affected email addresses end in @bitinternet.com, @btopenworld.com, and @talk21.com. Messages to these addresses will be queued at Oxford and delivery attempts will continue for 7 days. After this time your message will be returned to you with a delivery failure message. This affects personal and system-generated messages, including those sent via maillists. Messages sent to multiple recipients will deliver normally for other recipients.
We are in touch with BT to confirm and fix the cause, and restore normal service.
We are sorry for the disruption that this is causing, and recommend that urgent emails are followed up by telephone or other means. We will maintain latest information on this issue at https://status.ox.ac.uk/.
Users may occasionally experience some problems using Oxfile. This is a known problem caused by the load on the system resulting from backups being taken. Usually these interruptions are short-lived and users should just wait for ten minutes before trying again.
We do actively monitor these interruptions to the service and if they appear to be taking an unreasonably long time to clear, we will take appropriate steps to restore the service.
A longer term fix is currently in development and, once that work is complete, these disruptions will cease. In the meantime, we apologise for any problems these brief outages cause.
