I am going to be announcing two new prefixs into BGP soon and the netgeek in me is very curious as to the length of time it takes to show up in other parts of the world that're logically far from Hawaii. Instead of going to www.traceroute.org and refreshing repeatedly, I thought folks here might've created a tool to do just that. Or, perhaps, someone else has stats on a test they ran in the past.

Non-scientific test, but I've seen new prefixes appear at the Oregon-IX route server in <20 seconds (we're only in Texas), and reach a modestly steady state in <90 seconds. I've seen adjustments (prepending, etc.) appear in 45+ seconds, and withdraws in probably the same time.

I was hoping to query servers in different parts of the world: China, somewhere in Africa, places in Europe, etc. Does anyone have one already written? Both of these seem to be broken: http://www.ris.ripe.net/bgplay http://bgplay.uoregon.edu/bgplay scott
