Strange Latency Problem

For the last 2 weeks I have had a very strange problem with latencies especially to servers in the EU and US.

Usually; say I start off with a 290ms latency to servers in the US.
After about an hour - maybe less or more; slowly this latency will increase by about 100ms to say 370-390ms.

Now if I repeatedly reconnect using different dns servers on my internet connection dialer there is a fair chance that the latency will go back to normal after about 4-5 tries.

Here's a ping snippet where my latency was awful then i disconnect and reconnect twice to get back to normal latencies:

Code:

However even after doing this the latency problem slowly creeps in yet again after a completely random length of time typically between 15 minutes to 45 minutes and the latencies are back to being sh*t.

All of this doesn't seem to have much of a correlation on whether or not I'm downloading or torrenting anything.

I have used namebench to pick a good dns server and each time it changes. Regardless I have set up dialers for each of these servers; but the problem crops up in all of them.

1 more thing whenever the latency goes up like this my internet browsing speed goes down significantly with webpages often getting stuck loading.

Even worse now @ 7:16am

Disconnecting and reconnecting seem to alternate between latencies of 372ms to 464ms to US servers when it was 280 only 20 minutes ago.

"Destination net unreachable." is where I am disconnecting and re-connecting.

Speed to US servers is also really bad right now; this is at the 371ms latency above.

For the last 2 weeks I have had a very strange problem with latencies especially to servers in the EU and US.

Usually; say I start off with a 290ms latency to servers in the US.
After about an hour - maybe less or more; slowly this latency will increase by about 100ms to say 370-390ms.

Now if I repeatedly reconnect using different dns servers on my internet connection dialer there is a fair chance that the latency will go back to normal after about 4-5 tries.

Here's a ping snippet where my latency was awful then i disconnect and reconnect twice to get back to normal latencies:

However even after doing this the latency problem slowly creeps in yet again after a completely random length of time typically between 15 minutes to 45 minutes and the latencies are back to being sh*t.

All of this doesn't seem to have much of a correlation on whether or not I'm downloading or torrenting anything.

I have used namebench to pick a good dns server and each time it changes. Regardless I have set up dialers for each of these servers; but the problem crops up in all of them.

1 more thing whenever the latency goes up like this my internet browsing speed goes down significantly with webpages often getting stuck loading.

Even worse now @ 7:16am

Disconnecting and reconnecting seem to alternate between latencies of 372ms to 464ms to US servers when it was 280 only 20 minutes ago.

Thanks.Yeah 300-330ms to US east is definitely reasonable and understandable. It's just that occasionally latencies shoot up to 480+ms and this happens quite often at various times during the day especially during the early morning 7am-8am period.These times are accompanied by very low bandwidth and intermittent packet loss so getting anything done becomes a pain.As you said it's probably because of peak times in the US. However what's strange is whenever I get sh*tty routing to the US, EU routes also seem to be awful. I can't understand how it can be peak times at both places at the same time.Or perhaps it's just outgoing congestion from India to the EU/US region ?I've tried connecting to US west servers but they give almost the same and occasionally worse latencies than US East. Perhaps BSNL routes US west thru the NYC area ?150-200ms to San hose sounds amazing and almost too good to be true (with bsnl at least lol) but I'll definitely look at servers there.

It could be possible that BSNL is routing much of it's US traffic these days via Europe because it now has a share in the Europe-India gateway and it would surely be much cheaper for them to do so (at the expense of good routing to the US), but not being a BSNL customer and thus unable to do any diagnosis, I can only speculate on what they might be doing: this assumption is purely based on the trace-route you've provided in a previous post.

On the other hand, they're sending an awful lot of traffic to US backbones (Savvis, GlobalCrossing, GlobeInternet) so it's difficult to say who is at fault (the Internet can be a funny animal). In the trace provided, that traffic is being handed over to Tata/VSNL in Mumbai and on to Level3 in London, so it's got less to do with BSNL and more to do with Tata in this case because there is almost zero additional latency coming from Level3, it's all Tata. Based on that trace, there every chance that whoever is hosting Cnet.com isn't buying from the 3 providers mentioned above.

Strangely enough airtel routes most traffic to the US via pacific route through the west coast; although latencies there are higher on average than BSNL (when they keep their sh*t together, that is).
Airtel also seems to use less congested routes typically and very little packet loss if ever. Airtel also seems a lot less vulnerable to jitter and congestion or bad routing issues.
However Airtel has FUP and comes out to be almost double in terms of costs.

Kolkata doesn't seem to be many alternatives at all so I'm stuck with BSNL and a crappy airtel backup. Neither reliance or anyone else wants to setup shop here.

Hopefully more ISP's will eventually come here.

This is from today; after 8am; and It's 1:13am IST now so it's probably off-peak everywhere (early morning US early evening EU i think).

pings to cnet itself are excellent in the 268-276ms range.

Now here's airtel:

pings with airtel are in the 332-335ms range; and routing in this case is via the pacific/west coast. Slightly less jitter too.

----------

I think one of the biggest frustrations for me is :

1) There aren't any alternatives in Kolkata other than bsnl and airtel
2) Sometimes when the internet takes a massive dump; it seems like there is no one to talk to to get it fixed and tier 3 tech support is non-existent. Call center operators naturally have no clue about routing or latency issues :(
