Tracking down slow internet on SingTel Fibre to the home
SingTel makes big claims about the beauty of their fibre offering. I do not experience the claimed benefits. So I'm starting to track down what is happening. Interestingly when you visit SpeedTest, it shows fantastic results. I smell rat.
So I ran a test with Pocketinet in Walla Walla, WA. SpeedTest claims a 5ms ping response, but when I, immediate before or after such a test, issue a
ping -c5 www.pocketinet.comI get results rather in the range of 200-230ms.
Ein Schelm wer böses dabei denkt!
While this evidence isn't strong enough, to accuse someone of tampering, it points to the need to investigate why the results are so different (IDA are you listening?). So I started looking a little deeper. Using traceroute with the -I parameter (that uses the same packets as ping) I checked a bunch of websites. Here are the results (I stripped out the boring parts):
traceroute -I www.pocketinet.com 9 220.127.116.11 3.913ms 3.919ms 4.033ms 10 18.104.22.168 204.256ms 22.214.171.124 170.493ms 171.314ms traceroute -I www.economist.com 9 126.96.36.199 4.316ms 4.882ms 4.680ms 10 188.8.131.52 193.164ms 184.108.40.206 188.148ms 220.127.116.11 196.526ms traceroute -I www.cnn.com 9 18.104.22.168 4.772ms 4.679ms 5.160ms 10 22.214.171.124 171.006ms 126.96.36.199 187.336ms 188.8.131.52 171.447ms traceroute -I www.ibm.com 9 184.108.40.206 4.385ms 5.857ms 3.853ms 10 220.127.116.11 178.135ms 18.104.22.168 183.842ms 22.214.171.124 181.097ms
Something is rotten in the state of
Only Google bucks that pattern. But that's due to the fact that their DNS sends me to a server in Singapore. So the huge jump in latency happens in the 203.208.182.* and 203.208.151.* subnets.

So, the servers might be in the SingTel overseas location? InfoSniper sees them in Singapore (you can try others with the same result). Now I wonder, is the equipment undersized, wrongly configured or something else happening that takes time on that machine?
Looking for an explanation.
Update 19 Sep 2014: Today the speedtest.net site shows ping results that are similar to traceroute/ping from the command line - unfortunately not due to the fact that the command line results got better, but the speedtest.net results worse - Now ranging in the 200ms. I wonder what happened. Checking the effective up/down speed will be a little more tricky. Stay tuned
