Title: RTT to Syndey POP, via Tokyo??
Post by: Kendalbeefcake on October 14, 2019, 10:32:44 PM
Hi, I'm setting up a tunnel broker but the RTT to my local PoP (sydney) is hideous..It's been like this a couple of days so I'm guessing it's not a transient issue; the tracrt also seems to go via Tokyo?

I'm 20km outside of Sydney CBD, so I can't really account for latency.. Tracert below:



Tracing route to tserv1.syd1.he.net [216.218.142.50]
over a maximum of 30 hops:

  1    <1 ms    <1 ms    <1 ms  loosecanon.culture.net [RFC 1918]

 14   300 ms   299 ms   299 ms  tserv1.syd1.he.net [216.218.142.50]

Trace complete.

Neeldless to say it results in hideous performance; my throughput drops to about 500kbps to 4mbps from 47Mbps..

Known issue, or is the syndey POP just an illusion?

Same here. 250mS latency. From Melbourne to Singapore to Tokyo then to Sydney.

I think you could count the number of cables to the continent of Australia on your fingers, if not one hand, and a lot of those are so badly managed&maintained that a moon bounce could get better distance metrics
