Cat Telecom - Packet Loss And Terrible Latency

[kudroz]

I've been a customer of CAT Telecom (Chiang Mai) for about 1 year and a half. Always had good connections, now it's been a week and I'm experiencing about 7-15% packet loss when I reach a certain hop in Bangkok and I use to regularly ping one of my server in Las Vegas at about 230ms, not it's occiliating between 500ms to 800ms.

I was wondering if anyone else is experiencing such problems and/or might have a clue to what's going on. By the way, I live just next to the ADSL exchange point, and I have 4mbps/1mbps (CAT HiNet) connection.

Ping (count 100) to 66.209.64.238:

--- 66.209.64.238 ping statistics ---
100 packets transmitted, 89 packets received, 11% packet loss
round-trip min/avg/max/stddev = 531.467/560.897/750.769/33.024 ms

I also have a 2mbps/1mbps (TT&T Maxnet) and when I ping/traceroute 66.209.64.238 - I get no packet loss and the latency is about 290ms. Any help would be very much appreciated.

I had some weirdness so I checked... doing a ping google.com I get about 35% packet loss with CAT and 10% with TOT.

Should mention that my CAT is the EV-DO wireless card.

Something is really funky here

Could it be the sub-sea fiber cable damage off India and in the Mediterranean Sea?

Regarding the issue of low speed. Refer to on 30/01/2008 at 01:47 p.m. There is a network event with IIG link drop because of submarine cable problem at international portion that affects all users have a trouble when access International website and low speed. However, CAT Telecom Public Company Limited is solving the issue. After the issue has been solved, we will inform you as soon as possible

Got this from True when i emailed them yesterday about bas performance, latency and lost packets

I am experiencing severe packet loss problems on CAT HiNet by TT&T today, causing web pages to come up garbled 75% of the time. Posting on Thaivisa is a serious task because most of the time, once I click Add Reply, I get a blank page and the post has not been sent, or I get the Invision forum code from the background as a txt file.

At times today I have had pings over 1000ms and pages that stall having to reload.  been improving this afternoon.  Big supprise was how early in the AM it started so it must be maint. issue  ToT IpStar

[meadish_sweetball]

It seems to have resolved itself by now.

Latency TOT:

Latency CAT:

Packetloss TOT:

No packetloss on CAT over the last 24 hours.

Measurements are done from AMS-IX (Europe)

Looking at the results from Kudroz, I would say there was a problem between Changmai and Bangkok. The average latency on the CAT line is always 300-400ms (acceptible for me).
