Our infoBase and portfolio services on server SRV275 are currently experiencing problems. We’re investigating the issue.
Update: The server is back up and running. The webserver was experiencing unusual high load which caused a snowball effect.

InfoBase down for server migration
Thijs Welman
We’re moving InfoBase to a new server. This will cause the InfoBase website to be unavailable on Wednesday December 21st. We expect the main services to be available again around noon. The portfolio system will also be unavailable; handing in work will not be possible during the maintenance.
Update 12:30: InfoBase is up and running. However we still have some difficulties accessing the system from our other webserver(s). The submission portals and portfolio therefore are still unavailable. We’re waiting for our ICT department to make some changes to the firewall.
Update 12:50: ICT made the necessary changes. Everything is operational now. We’ll monitor the system the coming time for any problems that may arise.

BKTOI3 unavailable
Thijs Welman
BKTOI3 (blog.bk.tudelft.nl and adhok.bk.tudelft.nl) is unavailable since Sunday 20 November due to a problem at the central ICT infrastructure. The problem is being investigated by the TU Delft ICT engineers. Part of the storage infrastructure seems to be malfunctioning.
Update 21/11 12:00 – The problem still persists. Unfortunately we don’t have an estimated time to fix.
Update 16:00 – ICT confirmed that a piece of critical storage hardware has crashed and is malfunctioning. The vendor is working on a solution.
Update 18:00 – Several hard disks have crashed simultaneously. Chances are that the only option is to restore the system to a previous state in time from backups. All data (updates) since last Friday will probably be lost.
Update 22/11 13:00 – Still no news from our ICT department. We don’t have an estimate when the server will be back up and running again…
Update 16:00 – Just heard there are no backups of our affected server. They should be there, but the server was by mistake not included in the backup schedule. Chances are all data is lost. We’re making plans to restore the systems as soon as possible (but without the original content)
Update 24/11 – A glimmer of hope: The crashed hard-disk have been sent to the manufacturer and there is a bit more hope some or all data can be restored. We should know more on Friday. In the meanwhile most important functionality has been restored on a new server.
Update 25/11 – They did it! Seagate has been able to fix the broken hard disk and the ICT managed to get the old storage array online just long enough to get some crucial data. The data from our server has been restored and copied to a new storage system, which means our server is back up and running. We will be doing some rollbacks and merges in the coming days. The adhok website has been restored already.
