Hello
My computer can't access any sites hosted by dreamhost. I even can't access dreamhost.com, dreamhoststatus.com etc to report poblems. Does anyone have the same problems?

They had a DNS DOS attack:

I think it's over now as my sites are back up

My sites aren't up yet. I can't even access http://www.dreamhoststatus.com/2007/04/08/dns-issues-causing-possible-site-and-email-downtime/#comments
and their homepage. Too bad.

Thanks Olney and Mulligan for confirming..

From their site:

Downtime for several servers (http://www.dreamhoststatus.com/2007/04/07/downtime-for-several-servers/) Major DNS DOS attack (http://www.dreamhoststatus.com/2007/04/08/dns-issues-causing-possible-site-and-email-downtime/)

We are currently experiencing intermittent DNS outages on all of our nameservers, this is causing problems with sites and email functioning properly.
We think it might be the DNS load balancers we’ve recently installed but haven’t determined that for sure yet. More information will be posted as we have it.
Our apologies for the inconvenience this causes.


UPDATE (2007-04-08 03:20 PDT): It appears we are the victims of an Easter DOS attack against our nameservers, we have an admin at the datacenter and our network expert onhand to deal with it. Hopefully things will be back to normal shortly.


UPDATE (2007-04-08 04:54 PDT): We seem to have isolated and resolved the DoS attack for the moment. All of our DNS servers have been resolving domains correctly and without pause for the past 20 minutes now so it appears that this nasty episode is behind us. We’ll be mopping up and fixing servers that might’ve crashed or otherwise gone wonky in the interim. Again, our sincerest apologies for all the downtime.

That explains my low revenue this morning.

That explains my low revenue this morning.

Yeah it went down on the peak of Sunday Japan time...

Not really a scalable solution. If you are taking in 3 figures plus a day, just 1 day of outrage can buy you a couple years of hosting! :o

Easter Sunday was terrible for my revenue. No hosting issues. Just very low traffic.

In my case, since most of the domains in question are japanese, I doubt easter had anything to do with it. Pretty sure it is a dreamhost issue.

There are two things that can potentially cause this to happen.

.htaccess issues
Hitting Shared server memory limits
.htaccess issues
If the error happens instantaneously, then most likely the cause is something to do with your site's .htaccess file. Some potential things to look for:

Syntax errors in the .htaccess file
Custom PHP setup that isn't working
To see if this is the cause, try renaming the .htaccess file in your site's home directory to something like ".htaccess.disabled". If the problem is in your .htaccess file, that will immediately solve the problem.

Keep in mind that .htaccess rules apply to all subdirectories – so it's possible for an .htaccess file outside of your site's web directory to affect your site. Make sure you also look higher up in the directory structure for .htaccess files that might affect things and try renaming any you find in order to see if it helps.
