According to the article below, it seems the earthquake did do some damage to the undersea cables.

I thought so.....my problems started right at the time of the earthquake and were the kind of problems I'd never accounted before, like some websites fine, but others almost out but not totally down.

I'm having similar problems at home. If anyone has the time/cares, go to www.speedtest.net and try testing your bandwidth to Europe, the US or other countries. I've found that my connection is fine in Korea (to be expected) quite slow in the US, and really bad in Europe (try London..i'm getting .1Mbps/.5Mbps both up and down to London with pings approaching 1000ms).

My guess is the slower feeling is probably just increased latency to sites that routed through Japan. Although I don't have any results to compare it to, a traceroute shows google.com routing through NTT Communication's servers (hops 11 & 13) that were presumably routed through Tokyo before the quake:

Code:
jeremy@malleus:~$ traceroute -OA google.com
traceroute to google.com (66.249.89.99), 64 hops max, 40 byte packets

NTT noted (see http://www.us.ntt.net/) that the quake has impacted their network, so I assume similar slowdowns are occurring still on many other sites.

mines slow is sh*t...plus facebook is running like a dog with 1 leg. i.e. not very f*&%ing well

they just 'upgraded' so maybe this is making issues in performance too.

It was kind of okay yesterday, it's gone completely to crap tonight. I can't even get speedtest.net to load, let alone run a test. Most of my other overseas sites aren't working well either. Naver and the rest of the local sites are lightning fast as usual.

Really seems like it comes and goes. Last couple days its seemed like worst speeds are during Korean peak times. I'm guessing the tubes get clogged. Anyone been using battleping or lower ping? Interested to see how these services are affected.

I had thought it was because I joined the 'free' internet with SKT for having three family members on a contract. But I guess even if I did upgrade it wouldn't make a diff eh.

Mine's been on and off since the earthquake. Youtube is a dog tonight. It has downloaded only 27 minutes worth of video in about 90 minutes! Megavideo will download about 23 seconds of the new episode of Californication before crapping itself and stopping. Argh.... it's driving me crazy. However Australian news sites are streaming video with no problems at all.

Same problems, at home and at uni. Speedtest to the UK was never great, used to get circa 2mbps / 400ms ping but was just about enough to use iPlayer and most sites loaded fine. However, it's an absolute joke at the moment, just got 0.5 and thats probably one of the better results in the past week. Korean server tests are normal. Fwiw I have SK Broadband.

Just had a patchy Skype with a friend in the UK, he got 18mbps locally but tested at 0.8 to Korea.
