I was looking for reasons why my internet has been dragging a slower during the night. As I did some tests on speedtest.net it was very obvious that speed results with local ISPs are consistent with my advertised plan speed. However, speed results outside of the country are way out of what’s tolerable.

I began to search for my ISP’s local and international peering as obviously they should reveal what networks and what routes my ISP has from my end to the servers I am trying to connect to. According to Wikipedia via Google, my ISP should have an assign ASN (Autonomous System Number). To cut the story short, I found my ISPs ASN and others and ended up here http://www.robtex.com/as/ where I can query for an ISP name. So far I have found:

SkyBroadband (SkyCable)
http://www.robtex.com/as/as23944.html#peer

Globe Telecoms (G-Net)
http://www.robtex.com/as/as4775.html#peer

PLDT (Philippine Long Distance Telephone Company)
http://www.robtex.com/as/as9299.html#peer

You will notice that of the three, G-Net has the most number of peers. Look over at the graph tab and you will have a better idea of which other AS your ISP has direct peering with. Again, G-Net appears to have better peering internationally i.e. with Cogent and Level3.
