On November 28th 2014, we experienced some service interuption between 19:15pm and 20:00. Total affected period was approx 45 minutes.

The cause of the interuption was found to be a server within our own network engaging what appeared to be a DOS attack. The size of the traffic was sufficient to strain one of our routers as there was an excessively large number of small UDP packets. This caused some packet loss throughout the affected period. The level of packet loss varied throughout.

Having determined the source of the traffic, we were able to contain the issue by disabling the attacking server's network port. In order to expedite the return of normal network connectivity, the affected core router was also rebooted. The network was operating under normal parameters again by 19:55 HKT.

We would like to convey our sincerest apologies and regrets for any interuption to the network and any inconvenience this may have caused.
