ISLD had a short outage yesterday. I haven't heard of anything today, though, and I am able to get Island order book quotes through RealTick. May have been a problem earlier, as I wasn't really looking. They don't often have outages - this (yesterday) is the first alert I have seen in quite some time. Townsend, though, does have problems quite often with Island. I think sometimes they shut-down order book feeds for a while if their system gets too bogged-down. ---------- To: <subscriber@island.com> Subject: Island Service Interruption Dear Subscriber, This afternoon Island experienced a network related problem that affected subscribers attempting to enter or cancel orders. The problem occurred at approximately 12:53:26 PM (EST) and was resolved at 12:59:56 PM (EST). During these times, any orders or cancellations sent to Island were not accepted. Orders placed prior to 12:53:26 PM or after 12:59:56 PM were not affected. Specifically, this interruption was caused by a failure in Island's core matching engine. Island is designed with a failover matching engine which is always ready to take over in cases like this. Our current failover procedure was designed with a number of safety checks that took just over six minutes to complete. Obviously we know that even a six minute outage has a major impact on our subscribers, so we will continue to work on ways to recover from a worst-case failure like this in under a minute. Thank you, William Sterling Chief Technology Officer Island ECN
