Does WP MU no longer have a ping list?
 

I just realized that WP MU doesn't seem to have anyplace to put a list a sites that should be pinged when a new post is made.

Am I missing something here? I seem to remember there being a place to put a list of sites to be pinged under my old WP install.

Never mind. I just found this plugin to get the settings back.
Enable Site Ping WPMU

Anyone have a decent list of sites to ping? All the lists that I have seem to be full of dead sites.

While these aren't necessarily adult, this is the list I've used for a while:

now, for another project where I've done a lot more tracking of what works and what doesn't:

I need to merge those two lists and do more testing, but, those are about the most accurate ones I have.

Merged list of the pinglist I've had but refined:

I'm running some testing on the last one, will update this thread later after a quick spot check.

Removing the ones that come back with immediate errors, technorati's server appears to time out so I haven't removed it from the list as part of their network is acting really odd:

At this point, that list appears to be the most accurate one I've got.

That is some list :)

Is there a way of testing each link by putting it in a web browser or something? I've tried a few like http://rpc.blogrolling.com/pinger/ but all I get on that one is a blank page.

The 9 at the bottom are the ones that appear to respond successfully to a properly formed ping.

remove technorati, they do not accept pings anymore. I've found a number of other ping services that I'm checking now.

Yeah when I was moving links and stuff from my old blogs to WP MU I got the message that Technorati was not accepting new sites when I clicked on the add a site Technorati widget that had on my old blogs so I had a feeling that included pings.

After playing around with all this for the last 24 hours I'm really beginning to wonder if there is any reason at all to be using Rocket Pinger or to add more ping sites to WP since it pings http://rpc.pingomatic.com/ by default which seems to ping all the remaining ping sites.

Although if I hadn't spent the last 24 hours installing Rocket Pinger and that WP plugin and messing with all of this I would have never known what I know now and probably wouldn't have spent $57 on Rocket Pinger or installed that WP plugin.

I would think that rocketpinger probably isn't a good purchase. pingomatic does a pretty good job, but, I've found that in reality, pingomatic + google give about 95% of the traffic.

I see that Rocket Pinger has a place to put proxies. What would be the point of using proxies?

because some rpc services block the IP address that has communicated if pings from that IP happen to frequently. Using a proxy allows you to skirt those limitations. However, I doubt that is an issue with more than a handful of ping services.

So I guess you could ping pingomatic using one IP and the a short time later ping it again using a proxy although I'm not sure pinging the same url more than once would be a good idea.

It does seem like pinging pingomatic along with submitting a site map to webmaster tools is all that is needed.

you really want at least feedburner (a google property) and pingomatic (a wordpress property)

You don't want to ping too frequently, and really only want to ping when something is updated. Pinging twice doesn't really benefit things because it'll just grab the document and the guid (article unique identifier) will know it has already pulled it.
