Hello all... i'm experiencing a complete slowdown for the past couple of days... yesterday the open dns stopped working with my connection, that was resolved in the evening though... the speed is sometimes normal and at many other times its like 10 kbps

....

is any of you experiencing the same issue?? strangely the upload speed is the usual...

another strange behaviour is that some torrents (which should have been getting full speed; please i know all about torrents so no telling me the seed stuff n all

) are not getting any speed while others are continuin at the normal pace.

Three major undersea cables -- the Sea Me We 4, Sea Me We3, and FLAG -- were cut, considerably slowing down India's internet and voice traffic. The extent of the damage is still being assessed.

The voice operations (call centres) of IT-BPO firms comprise around 20-30 per cent of most firms in India, and get hit the most -— especially if the International Private Leased Circuits (IPLCs) are down too. An IPLC is a point-to-point private line used by an organisation to communicate between offices that are dispersed throughout the world.

Consequently, it's generally the smaller business process outsourcing (BPO) units that get badly affected. The larger ones have built-in redundancy that does not make them very vulnerable. They also have connections from both the Pacific and Atlantic routes so if one route is affected the load automatically gets transferred on the other route.

Moreover, those firms that have delivery centres around the world will not be affected as much since they can divert some work to other centres. Moreover, a considerable amount of high-end analytics work can be done offline.

Fibres cut in recent years:

- January 20, 2007 - Due to Taiwan Earthquake
- January 30, 2008 - in Mediterranean Region
- Now December 19, 2008 again in Mediterranean Region
"Being a Saturday, we may not feel the full impact of the cuts. Though there's no doubt that traffic has slowed down to a snail's pace. Moreover, given the global slowdown, most companies themselves are going slow, and hence the impact may be lower. However, what is surprising is the regularity with which these cuts have been happening," said Rajesh Chharia President, Internet Service Providers Association of India (ISPAI), told Business Standard.

A statement from France Telecom said the Sea Me We4 could be up by December 25, and it hoped the overall situation would be back to normal by the end of December. The causes of the cut -- located in the Mediterranean between Sicily and Tunisia, on sections linking Sicily to Egypt -- remain unclear.

France Telecom said it immediately alerted one of the two maintenance boats based in the Mediterranean area, the "Raymond Croze". In its initial assessment, the company listed 14 countries affected by the current problem. The Maldives are 100 per cent down, followed by India, which has 82 per cent disruption. Qatar, Djibouti and the UAE were the next most widely affected areas with about 70 per cent service interrupted. Disruptions for Saudi Arabia, Egypt and Pakistan range from 51 per cent to 55 per cent.

Impact on voice traffic:
- India: 82% out of service
- Saudi Arabia: 55% out of service
- Djibouti: 71% out of service
- Egypt: 52% out of service
- United Arab Emirates: 68% out of service
- Lebanon: 16% out of service
- Malaysia: 42% out of service
- Maldives: 100% out of service
- Pakistan: 51% out of service
- Qatar: 73% out of service
- Syria: 36% out of service
- Taiwan: 39% out of service
- Yemen: 38% out of service
- Zambia: 62% out of service
Most of the traffic between Europe and Asia is re-routed through the US. Traffic from Europe to Algeria and Tunisia is not affected, but traffic from Europe to the Near East and Asia (incuding India -- see table) is interrupted to a greater or lesser extent.

The (SEA-ME-WE) SMW-3 and SMW-4 are owned by groups of phone companies including Bharti Airtel while FLAG cable systems is owned by Reliance Globalcom (an Anil Ambani owned company). And it was only this February, that damage to the trans-Atlantic submarine (undersea) cables slowed down Internet traffic and affected IT-BPO firms for almost three weeks across India before they were reparied, even as Indian telecom operators were diverting traffic over alternate routes.

Call centres of IT-BPO firms were the most affected then, since the IPLCs were down too. Unsubstantiated sabotage theories were doing the rounds too.

Submarine cables are laid beneath the sea to carry telephone and Internet traffic. They can be broken or damaged by fishing trawlers, anchoring, undersea avalanches and even shark bites. In 2006, an earthquake centred near Taiwan had severed several undersea cables, and Internet services slowed to a crawl across major parts of Asia.

In February, a storm struck the Egyptian coast on January 30, making it impossible for ships to dock at the Alexandria port. This prompted some of the ships to anchor off seas, and it is believed a ship dropped its anchor right on the top of the submarine cable channel.
How are undersea cables repaired?

- Find the location of the accident; drag the damaged part to the surface, and replace it with a new stretch of cable
- May also send light pulses along the fibres in the cable to determine the exact location
- A working fibre will transmit those pulses all the way across the ocean; a broken one will bounce it back
- The telecom operator then sends out a large cable ship with a few miles of fresh fibre-optic lines
- If the faulty part of the cable is less than about 4,000 feet down, a submersible robot can be sent
- The robot finds the right place; grabs hold of the cable; cuts out the malfunctioning section, and pulls the loose ends back up to the ship
- Robots do not work in very deep water. In such cases, technicians use a grapnel to cut the cable and hold it
- A skilled technician (jointer) splices the glass fibres; uses adhesives to attach the new section of cable
- The repaired cable is then lowered back to the seabed on ropes

also the browsing speed is noticeably slow for many sites....

i was thinking something like this had happened.

... thanks for the update admin

Admin · 12-20-08, 10:37 PM

My tata wimax has been worse then your connection... yesterday I was stugeling to open google home page. Its a bit better today and I suppose as people start going to sleep it would get better like it did yesterday

shomitsarkar · 12-20-08, 11:02 PM

Thanks for the update...u have been really informative .....that means bad news for me ..no gaming for a about a month

Admin · 12-20-08, 11:32 PM

Find playmates from singapore, thailand, Australia or Newzealand and you wont experience any lag or slow speeds.
There must be gaming servers in Hongkong sort of places as well where there is hardly any impact.

StarK · 12-22-08, 08:16 PM

Ok so the repair ship has reached the accident site to repair 2 of the three cuts... Repair crews reach underseas cables in Mediterranean after Internet communication cut -- chicagotribune.com

the best bit is that the third cable belongs wholly to Reliance

, don't think these nutheads are going to repair it soon

... they also coudn't be contacted for comment!

check out the drastic drop in dns requests on opendns on the days of the accident.. !

(extreme right

peaceful_perdition · 12-23-08, 08:39 PM

i have been experiencing the same problem as well. my question is that everyone says that their torrents are working as usual but mine arent. I am on the 799 plan so i should be getting download speeds of around 30-35 kbps but i am only getting around 20 kbps

i did send a mail to customer care yesterday and got an automated response that said that they'll get in touch with me within 24 hrs. that hasnt happened.

any ideas?

don't worry the same is happening with me too... m getting about 12KBps if connected to 1 seed (talking bout private trackers) and about ~23 when connected to 2 or more.

normally i got speeds like 35KBps...till that fateful day

...

peaceful_perdition · 12-24-08, 03:41 PM

ITS BACK!!!!!

woohoo.!!!!!

Download speed is ok , surfing is super slow !!!

adi231189 · 12-28-08, 09:41 PM

Download speed have been rectified but the surfing speeds are still low and if u call the CC no. it will tell u that it is due to cable cut so it has not been fully rectified

dndutch · 12-29-08, 10:13 PM

download speed is not only slow but download and even browsing suffers from Major disconnection every few mins. thats damm irritating.

StarK · 12-30-08, 06:17 PM

down speeds on my torrents have again fallen like those days..

now are they deliberately throttling our speeds??

have the cables still not been fixed? my speeds had returned to quite normal on 25th dec

linusr · 12-30-08, 08:04 PM

rapidshare downloads are realllllllly slow

& so does the sufn speed

dndutch · 12-30-08, 09:56 PM

linsur not only rapidshare but from few days i m trying to download the last part of a movie from megaupload and after 3-4mb it starts getting disconnected grrrrrrrr

This is sick. Seems they are playing at the backend. its better to reduce the speed and remain consistent with it rather then disconnecting every few mins. you end up doing nothing that way.

linusr · 12-31-08, 04:09 PM

torrent seems to be an better option

jakemake123456 · 12-31-08, 06:02 PM

Today I got a call from Airtel Tech Support in Bhopal , wonder why it was Bhopal when I live in Pune , anyway , he was asking if my internet connection is ok or if I am facing any browsing issues , I informed the executive that download speed is perfect but browsing is very slow in response he said that they found another crack in the Mediterranean undersea cable and that the ETA is by 4th of Jan 2009 , if I still face problems with browsing then I should contact Airtel CC in Pune .

, BSNL should start something like this .

adi231189 · 12-31-08, 07:58 PM

ok i heard that there has been another cable cut of the previous one which was fixed and it will be fixed in the 1st week of jan and could this be the problem why i am getting slow upload speeds no trouble with downloads in RS getting 50KB/s in my 384kbps plan.

pisces_m · 12-31-08, 08:52 PM

Its not due to cable cut. If you are in delhi. In many parts of delhi around 25th the servers were being upgraded and my speed was halfed for 3 days. It was visible mostly on browsing. I calles up customer care and they clarified that servers are being upgraded to handle increased load and at the moment backup servers are working and it will get rectified by 28th december and now its woeking fine. on my 256kbps UL i am getting 300kbps download and 260kbps upload.
