Hello all, Ever notice that sometimes sites located in SG take a while to load? Sometimes we see weird routing where the packets get routed to the States only to come back to Singapore (see traceroute below).
I'm trying to see how often this actually occurs, so I've created the following script: http://haller.ws/projects/sg-interconnectivity/routing-data-capture.sh to traceroute to the ~400 netblocks in Singapore and then upload the results to the data directory at: http://haller.ws/projects/sg-interconnectivity/ If you could help out by running the script on something with bash installed, that'd be great. With the results, I'll publish a SG connectivity map and it'll help us understand how widespread this phenomenon is. Thanks, Patrick Host Loss% Snt Last Avg Best Wrst StDev 1. sw-sv-10.ofs.edu.sg 0.0% 6 2.4 2.4 2.3 2.6 0.1 2. fw1-svcint.ofs.edu.sg 0.0% 6 0.3 0.3 0.3 0.4 0.0 3. ofsgw-fe0.ofs.edu.sg 0.0% 6 0.8 0.9 0.8 1.0 0.1 4. s5-0-1-8-r10.cyberway.com.sg 0.0% 6 6.2 4.3 2.5 6.2 1.7 5. 203.118.7.14 0.0% 6 2.5 3.3 2.5 6.8 1.7 6. 203.118.3.227 0.0% 6 7.6 7.1 5.1 9.3 1.5 7. so-7-0-3.edge3.SanJose1.Level3.net 0.0% 6 210.4 224.7 209.3 266.9 24.4 8. ae-22-79.car2.SanJose1.Level3.net 0.0% 6 209.5 217.1 209.5 238.9 11.3 ae-32-89.car2.SanJose1.Level3.net ae-42-99.car2.SanJose1.Level3.net ae-12-69.car2.SanJose1.Level3.net 9.
