To extend the available bandwidth of Jacobs University's Internet connection, hardware and network maintenance is needed. This operation involves replacement of physical devices and recabling, there will be no Internet network access during the downtime period.
THERE WILL BE NO INTERNET NETWORK ACCESS AT JACOBS UNIVERSITY ON WEDNESDAY, JANUARY 16, 2019, from 18:00 to around 19:00.
No "Internet network access" means, that there will be no services available, which are hosted off-Campus, e.g. there will be no Google, YouTube, Dropbox, Office 365, Onedrive, Nextflix, Spotify, and also not Jacobs University's web site.
Local services, like file access to files stored on Jacobs' file server, the CampusNet web site, the Exchange mail server will still be available.
The actual downtime will probably not last longer than 15 minutes.
If you have questions regarding your server(s) or network access, please contact Service Desk for Faculty and Staff.
UPDATE 2019-01-16, 19:05
Network access has been restored successfully.
UPDATE 2019-01-16, 20:10
Unfortunately there had been 3 further interruptions since 19:30, lasting 19 and 8 minutes, until 20:06. These were caused by a misconfiguration of routing destinations in our high-availability setup for our external firewalls.
On the bright side: The total bandwidth available for all Jacobs users has been increased from 1GBits/s to 3 GBits/s.
