Dear all,

Thank you for your understanding.

There was a unscheduled network disruption on 15 Apr from 5:24 am to 9:24 am.  COM2 Basement, level 1 and 2 network access affected.  The problem was due to emergency power source trip causing power trip in one of our COM2 wire centre.  The situation has been normalized on 15 Apr at 9:24 am.

Dear all,

There will be scheduled network maintenance as follows:

Date: 11 April 2013
Time: 7pm to 7:30pm

During this maintenance, wired and wireless access for certain network points in COM1 Level 2 and 3 will be disrupted for about 5 mins. The network points are C-3R-2-x to C-3R-3-X. The purpose of this maintenance is to reboot a faulty edge switch. Thank you for your understanding.

Dear all,

There will be a scheduled maintenance on COM1 wireless network and SoC websites as follows:

Date: 7 March 2013
Time: 7 pm to 8 pm

During this maintenance, wireless network access for COM1 and access for SoC websites may be intermittently disrupted. The purpose of this maintenance is to migrate Wireless LAN Controller and load balancer to another edge switch.  Thank you for your understanding.

We regret to inform that there is currently an unplanned disruption to our wireless access service. Our network is unable to communicate with ComCen's authentication server. The problem started at 18:31. We have since escalated the issue with ComCen and they are working on rectifying the problem now.

Other services that depend on NUSNET authentication may also be affected. E.g. SoC VPN.

Thank you for your understanding.
