It would be vastly more beneficial to post a link to the instructions than simply repeatedly posting:
"if you have a custom domain, pls send an email to help@posterous.com for instructions; otherwise u should be up in 1 hour"
Can't say I'm impressed with how they are handling the PR aspect of it.
I don't see a single tweet explaining what they changed (they mention IPs, did they change IPs, IPs for all servers, or just bring up additional ones) or why it is that custom domains are affected (I'm assuming it's an IP change, but is this a permanent change, or one I can just ride out).
I also don't see an actual announcement other than the @replies, although it's possible it's buried under those. As I'm not a frequent user of Twitter, I'm not aware if there is a way to filter out the replies and see only the useful content.
*edit - after typing that Posterous "finally" started responding again, so I can see what the blog post said.
It will affect how people perceive your product and your ability to continue to provide it. If they want to monetize, they need customers.
We're not talking about a major undertaking. Simply providing useful information in the main avenue they have open during the DDOS seems like a pretty straightforward thing to me.
Ironically, I came to ycombinator first to see what the status was and didn't even have to click through to "new". :-)
