Another fiber cut near Taiwan ? due to Typhoon Morakot ?
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Anyone in the know ? I can't find any published reports, but multiple internal reports of massive congestions from South Asian region to the US, and failure alarms. Given that Typhoon Morakot made landfall near Taiwan yesterday, this could impact APCN2, C2C, EAC, SMW3 amongst others. any updates are appreciated. - -gaurab -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.8 (Darwin) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAkqCWokACgkQSo7fU26F3X1lcQCeIC1V9cuiFTvBW1NPire1DMlh CP0AoMJaXrKVllZnsSX3vHfCP6nN1oAl =1xDM -----END PGP SIGNATURE-----
Hi Gaurab, How are you? Thank you for your help to install I-root. Actually I don't hear any damage info about submarine cable in Taiwan, and it seems fine from Taiwan to Internet now. cheers, Ethern ============================= Ethern Lin <ethern at ascc.net> Network Division Computing Center, ACADEMIA SINICA Phone: +886-2-2789-9953 Fax : +886-2-2783-6444 ============================= On Wed, Aug 12, 2009 at 2:00 PM, Gaurab Raj Upadhaya<gaurab@lahai.com> wrote:
I'm seeing high latency and some packet loss via multiple providers from the US to Singapore, matching what we saw a few days ago although not as bad (ie, packet loss is only about 5%, down from the 40% we were seeing a few days ago). At that time the cause was a cable fault somewhere in/near Japan, but at this stage I'm not sure if this is the same problem or not. Scott.

Now confirmed that APCN2, C2C and EAC are cut. also unconfirmed reports of SMW2 and SWM3 are out. FLAG and TGN seems to be not had any issues so far. It seems at this point, the fault is more on the South China Sea and the alarms I got seem to confirm that. For the geography, see http://en.wikipedia.org/wiki/File:South_China_Sea.jpg Circuits from Japan to SG, TH, PH are down, but not to HK. My perspective, yours may vary. - -gaurab -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.8 (Darwin) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAkqCaKoACgkQSo7fU26F3X2u5ACg7Hpy9jVwHNzdDTWI6wSu4Qyh TiMAn21dcEPKOqkdlQN9rQLFz+NypgID =DKT6 -----END PGP SIGNATURE-----
Update: The submarine cable down first is EAC since 8/9. FNAL down today(8/12). The cause might be typhone Morakot. Hongkong seems the most critical impact by these cable down. cheers, Ethern ============================= Ethern Lin <ethern at ascc.net> Network Division Computing Center, ACADEMIA SINICA Phone: +886-2-2789-9953 Fax : +886-2-2783-6444 ============================= On Wed, Aug 12, 2009 at 10:14 PM, Ken Gilmour<ken.gilmour@gmail.com> wrote:
Actually I can't tell you more about this. I am just have this info from my IPLC provider, and its just a gossip, not formal one as I mention.<grin> Its just happened that one cable system down on 8/9, the exact day of typhoon attacked Taiwan quite badly. Maybe someone can share more detailed info and we can wait for more info later. cheers, Ethern
Latest news: The typhoon Morakot cause rare debris flow under sea and damage many cable systems at southern Taiwan more than earthquake at 2005/12/25.
