ASX shutdown for 4 hours on option expiry day. http://www.abc.net.au/lateline/business/items/201110/s3350037.htm http://www.abc.net.au/lateline/business/items/201110/s335003... Also, so did HKEx (for the entire day, on option expiry day!) due to a typhoon (?), as far as I recall. This is non-news. Exchanges do stop trading unexpectedly sometimes and it's hardly specific to Russia. I'm not sure what was the submitter's interest in it.

I posted here because I find the HN crowd to be ahead of the curve on news like this (security, tech, etc). For example, previous posts have called this out as a non-event, which I found informative. I learned that exchanges are not as fault-tolerant as I thought. That is why I posted.
