Tot Adsl: International Slower Than Ever!

[samsara]

From Monday-Thursday of last week I noticed ping times were ALWAYS around 340 (which is the best I get) regardless of time. Before then, they peaked from 12-6 am, and went down to 650 ms or so from noon-8pm. NOW, ping times are always at 520 or so and DL/UL is REALLY slow. were talking 80/20 here. before, id never get below 250/40 no matter what it was. <deleted> is going on? cant stream a thing, cant play on xbox live; but then page loading times have actually improved for the most part.

any clues out there as to what has happened?

any ideas? it has NEVER been this bad.

[toptuan]

Can't help you, but I can commiserate: I have TOT ADSL and absolutely dismal performance. Trying to stream YouTube is a joke, many websites just stall when trying to open, and show an error message.

Never had this bad of performance except for the three weeks following the 2004 tsunami in which the underwater cables were damaged. The recent cable breaks (Mediterranean and near Taiwan) were all supposed to be fixed by now.

[samsara]

It was pretty much back to normal there for a week or so following the cable breaks, then this...so frustrating to not be able to depend on anything!!

Just want to ask you guys to download the prog Sam Spade from TV Download and run the tracert and other utils with it.

Tested a bit around and found out that it is the CAT Gateway which is slows down all traffic.

At that moment the tracert comes to 202.47.x.x all speed slowing down and that IP is the one from the international Gateway of CAT!

Check it out and please let us know your results.

Cheers.

TOT has been re-assigning IP ranges over the last 3 weeks. Next to the 125.24.x.x and 125.25.x.x ranges, they now also use the 118.73 range. I couldn't find any problems with the TOT-CAT connection, the response times on the TOT backbone are already very high. For comparison I added a traceroute from a CAT line below - with quite some big differences!

I think that TOT is trying to change *something*, probably by trial-and-error. Avarage packetloss between Thailand and Europe was 30% during 2 weeks until a few days ago. Average delay during the same period up to 1200ms which can lead to unavailable websites (but they're still there).

As usual, nobody will tell what's going on exactly. Because nobody really knows (I'm talking Thai engineers now). Let's all just hope that their trial-and-error way of working will soon lead to improvements!

The following graphs are measurements from Europe (AMS-IX) to TOT Thailand.

The traces don't show the actual path in Thailand, since the first hop is the other side of a PPP connection, which actually is a L2TP connection over several backbone routers. The delay to that first hop is a good indicator how the ISP backbone is performing (and CAT rocks, TOT sucks). The TOT traces are from Koh Tao, the CAT trace is from Koh Samui.

The one thing that i've noticed is that most of the traffic has been routed thru the Korea/japan/America route to europe rather than the middle east.

Thats the LOONG way around and does explain the high pings.

I'm assuming that someone at Cat hasn't thought to route the traffic BACK after the break was fixed.

Most traffic to Europe gets routed over the USA, probably because that's where the majority of the main internet pipes go to!

Resulting in high latency, since the distance to Europe over the US is triple the distance when routed directly...

The last few days here in Pattaya have been the worst ever, even when I was on 512/256 (now on 2048 - )

Last test was 104/110 about 2 minutes ago. Bangkok showing 1700/2??

Utter shit.

Like others commented, I cannot download anything, IE and FF blow up after sticking for ages.

Anyone get any sense from TOT ? Only joking !

[monty]

I'm not complaining! My international speeds are generally just slightly slower lower then my local Thai speeds...

Monty,

How are you getting those speeds. I'm in Pattaya on TOT 2048/512 and have just got

Ping 501 ms

Down 610

Up 324

using LA as the server just as you did ?

Cheers

No problems at 4 in the morning.

Monday and Tuesday, my TOT ADSL was down 75% of the time here in Pattaya.

From Monday-Thursday of last week I noticed ping times were ALWAYS around 340 (which is the best I get) regardless of time. Before then, they peaked from 12-6 am, and went down to 650 ms or so from noon-8pm.

This is actually tested on BTV cable internet. They have corporate CAT internet (4mbps/1mbps) feeding the cable, on which up to 10 BTV subscribers can be online.

Works good enough for me.!

Pretty stable throughout the day as well.

Historically I would agree with you that around 4/5am download speeds increased massively (used to check on torrents) but nowadays it is the same crap 24/7.

Don't suppose anyone has a useful number to call ?

1103 is the TT&T number to call. I did that a couple of days ago when the international access completely stopped. Normally there is a recorded voice, menu options, numbers to press for the next menu, etc, but this time there was a recorded message in Thai and then it hung up. It was as if they were saying "Sorry, help line is closed". Marvellous. TiTT&T.

Customer service?

At least the "IT hub of Asia" joke has finally died a death. I was receiving 80kbs this morning and the worst was 22kbs on speednet. Myspeed didn't even say it was a fast connection and it asumed I was on 28kbs dial up.

Azerbiajan steaking far into the distance as far as here is concerned.

Hope Thaksin sells off TOT and the whole bunch are sent out to sell noodles on street corners which is probably as far beyond their capabilities as providing a telephone and internet service.

Go Thaksin go!!!
