SAT-3 problems cause Internet chaos

Hmmmmm yes, had high lats on ALL cod w@W servers (400ms) high.

And I havent recieved some emails people sent (I'm gmail)
 
Many problems, had a few people add me as a friend on facebook, after clicking accept facebook gave a error "oops something has gone wrong, try again later" then all those friends did not get added and disappeared...
 
Having issues with my sites, using OpenDNS and name resolution is taking forever and mostly timing out
 
had huge connectivity problems to gmail and yahoo...mails not sent/received.
 
According to fairly good sources...

SAT-3 has actually been down for a couple of days. It was routing via protection on SAFE, where it switches to SEMEWE-3 and rides back to Europe. The SEMEWE-3 cable had a problem, breaking the protection. THAT is what has now been repaired, which is why the latencies are still higher than normal since the traffic is going via Malaysia.

SAT-3 itself could still be out for a while.

As I say, the information came from a source, I cant confirm accuracy.

First useful post that actually makes sense of it all - none of us have any idea what "Segment 14 of SAT-3, about 627 km from the ACC Beach Manhole" is supposed to mean. I was wondering how the latency could be around 400ms, not be going through SAT3/SEACOM, and also remain below the ~650ms satellite estimate. Had to be SAFE and then routed back through Malaysia. Thanks for the heads-up Andrew :) Any idea what the capacity of the SAFE cable is?

I believe theoretical capacity is around 120gigabit, but keep in mind, both safe and sat-3 are largely lit as bundles of STM-1s and are also used for carrying MUCH more than just your normal ISP data.

Hard to know exactly how much capacity is there and whats used or not

If the sources are correct that SAT-3 is down, chances are SAT-3 is also carrying a lot of international voice traffic

Yes indeed. The ping the last couple of days to the UK was the same as to US. :sick:
