High traffic from officecdn.microsoft.com RRS feed

Answers

  • Hi,

    So you have observed huge traffic coming from officecdn.microsoft.com. Do you have click-to-run version of Office running on your computer?

    If you are using a click-to-run version of Office, Office update service runs as a scheduled task daily to check the Office 365 service, http://officecdn.microsoft.com/ for new updates.

    When the latest update is available, Office will schedule a time randomly over the next few days to download and install the update. That's probably why you saw a high traffic from this server.

    Although the default is to download updates directly from the CDN server, you have the option to configure Office to retrieve updates from a local network share. This can be done via the following policy setting:

    Hope this helps. Let me know if this is not your case, feel free to post back with more details, we'll then take a further look.

    Regards,

  • Ethan - thats great, but we've confirmed with detailed firewall logs, TWO users with incoming traffic of approx 310-330GB EACH in the last 7 days to the MS CDN site. Unfathomable. Googling around, others have seen this too.

    Is this a download failure retry loop or something? This site is in south america and traffic shaping is only a bandaid, it shouldnt be doing this quantity in the first place. Any Solutions like reinstall or ?

  • i made a firewall block to *.edgesuite.net/*

    this seems to stop the traffic. users were eating all our internet bandwidth….
