The site is almost dead. Is there an alternative download site for their issues?

That caught my attention :) The

That caught my attention :) The site is hosted from eight different data center locations around the world. I checked each site, CPU load is fine, no memory issues and bandwidth utilization hasn't exceeded 20%. So the site isn't dead.

Can you drop me a quick email (buswellj at o3magazine.com) with your IP address (www.whatismyipaddress.com will tell you), and I will see where you are being routed. We've had a couple of issues in the past where a small number of users are in a subnet thats supposed to be in Asia, and its really allocated to some other company in Seattle. That doesn't help the users who get routed to the data center in Hong Kong instead of San Jose! :)

Drop me a note and we'll get it sorted out.

Thanks

It came right by itself after about

It came right by itself after about 20 minutes of going nowhere. When they did download, I was getting them at about 50k/sec each but thats just my terrible internet here in New Zealand.

I can still do that if you want, but I'm not having issues anymore.. unless you count having to read 8 issues as having issues ;)

I got your email, I'll take a look

I got your email, I'll take a look at the logs and see where you were ending up. Being in New Zealand, I would imagine you probably were getting sent to the APAC group of servers. But 50k/sec isn't great, I'll have a look and see if we can find a reasonably priced provider in New Zealand. I assume Australia would be reasonably quick from New Zealand as well?
