    UPDATE Friday 7/1. The delays cleared last evening. Microsoft issued an alert to their customers: "we're continuing to revert a recent update which may have caused the infrastructure to operate below the expected threshold".The effect on CUIT systems was only that mail was queued up for several hours while re-trying delivery to the gsb.columbia.edu and sipa.columbia.edu Office 365 systems. Email is always re-tried for 3 days, so our servers automatically sent out to those systems once they were available.

    ------

    UPDATE 13:00. The unofficial source downdetector.com has about 100 reports of Outlook 365 problems since about 10:00 this morning. [correction: originally misstated as 1,000]

    ------

    UPDATE 12:45. A few messages have gone through to sipa.columbia.edu but for the most part the outlook.com system is still giving the temp fail for both subdomains.

    ------

    Email for addresses @gsb.columbia.edu and @sipa.columbia.edu, both hosted on Outlook 365, cannot be delivered at this time. The outlook.com mail server is returning "Temporary server error". The email is being queued and retried on our servers and will go through automatically when the outlook.com server is able to take it.

    This affects cases where mail is sent to address @columbia.edu and has to be re-sent to those subdomains.

    UPDATE The certificates were updated at 12:55.

    ----------

    The SSL certificate for send.columbia.edu expired at midnight last night. The new certificate was not installed ahead of time, and for that reason users may have seen errors when sending mail this morning, if they use a client that connects to send.columbia.edu to send mail. Almost all users now send with Lionmail or Exchange (Outlook) and they did not see errors.

    We apologize for the delay on this routine work. The new certificates are being verified now and will be installed shortly.
