Internet Disruption

On Friday our internet provider suffered from denial of service attacks (DoS):

169535 – 04/12/2015 – 16:40  – Major Incident affecting Multiple Janet connections

The Janet network has been suffering from further denial of service attacks. The network is beginning to look more stable.

Janet engineers and security teams are investigating further to set up further preventative measures.

This is what caused our internet disruption, they believe everything is stable now.

Although I think things are still a bit slow this morning.

Partial Power Shutdown 14th July

The power shutdown on Tuesday 14th July will require the power down of all devices in Node 2 (218) which include, but may not limited to:

  • NAS storage servers (Buffalo and Netgear), so most CHSRV-??? storage will be down.
  • Main chemistry server ( – affecting network shares for the Office, Stores, and any group, staff and web file storage etc. Also some pages for the school on the University website will be unavailable.
  • Network connections in many parts of Purdie will be down. The server and NAS storage will need to be shut down in advance of the power shut down. I am planning to schedule this for 5 pm on Monday 13th. They will not be available again until power is fully restored, estimated for 9am the next day.

Please ensure you save any work that may be affected this loss of storage before this time. Also do not run any instruments that would require to write directly to these storage devices during the down period.

Network connections, internet and other university systems will remain available till the power off on Tuesday morning.
