PSN Speeds, Youtube Speeds

Post by Soliah » Fri Jul 03, 2009 2:48 pm

As of late (maybe within the last few weeks) I've noticed a massive slow down with Youtube and PSN downloads. This doesn't happen during peak times. Peak times my speeds are fast as ever, over 1MB/s.

Last night I tried updating my PS3 to the latest version of firmware and it was going at around 100KB/s. I decided to cancel it and do the update during peak times and it was fast as ever, pulling in at about 1MB/s. This also applies to games/videos I'm trying to download off the PSN. Slow as during off peak, but blistering fast during peak.

And the same applies to Youtube. Extremely slow, with me waiting for even a few seconds to buffer, but no wait at all during peak times.

Maybe a month ago this wasn't a problem whatsoever (and I haven't had any issues since the Optus backhaul international speed issue of a few years ago), so I'm just wondering if there were any changes on the Exetel side, or perhaps my exchange (Miller NSW) has now become a little bit congested, or the backhaul is congested?

So it's past midnight and my speeds have plummeted. Should normal traffic be affected by the Netenforcer? I thought it was just P2P.

http://www.speedtest.net gives me:

And Exetel's internal speed test gives me:

I sync at well over 10 Megabits/s and during peak times have no issues with speed.

Even streaming Apple trailers which use to go full speed during off peak is now slow.

Should I raise a fault ticket?

Youtube seems to be fixed tonight! (Though not as fast as peak). I can actually watch videos in HQ.

http://www.apple.com/trailers is slow though :\

It shouldn't be, but off-peak downloaders also use HTTP servers for downloads. The underlying cause is simple: a surge in demand post midnight + fixed bandwidth = lower speeds. The magnitude that you experience is very severe however, and is disproportionate to the general surge in downloads (which from http://public.mrtg.exetel.com.au/bwsumm ... width.html looks like a 25% surge?). This might suggest an additional bottleneck at your exchange level.
