Most third party clients can't connect anymore, MSNP18 is gone.

Current situation

The MSNP18 protocol and all the older versions are gone. MSNP21/22/24 are still there.

Most clients still don't implement newer versions. Some are listed on the right column.

What clients work

(Missing anything in this list? Pull requests welcome!)

Skypeweb based clients (not MSNP, but close enough) Official clients:

Needlessly detailed server status #

Updated every 60 minutes.

May have a few minor mistakes (due to packet loss, etc). Scroll down for reference.

April 2017 update: The bay datacenter is gone and was replaced by co4. Fixed db5 IPs.

May 2016 update: The bn1 and db3 datacenters are gone, at least for msn, and were replaced by bn2 and db5. I thought they were broken, like many servers of the list were already - repurposed for unrelated things. So now we have fresh IP lists and everything is green again.

Port 80 and 1863 are no longer tested against. MSNP22 scanning was added (because it's an one line change), and MSNP18 is kept in the table but not actually scanned.

Looks a lot less dead now!

Reference #

bay Server region codename (first three characters of the hostname of each of those servers)
Highlight The highlighted rows are the main servers of a region, which redirect to the rest.
:80 (No longer scanned here) HTTP port open. This is what you'd use when enabling HTTP method in old clients.
:443 HTTPS port open. Same as above, but not all clients use this. Newer versions of official clients use it (including WLM 2012, the windows 8 messaging client and skype)
:1863 (No longer scanned here) MSNP port open. The good old standard msn protocol port.
MSNP18 (No longer scanned here) Sends VER 1 MSNP18 to port 443 to test if the server still supports that version (the most common one among third party clients). Also helps check for false positives
MSNP21 Same as above, but sends VER 1 MSNP21 instead, to port 443. This version is not very common among third party clients (Windows Live Messenger 2012 uses it)
MSNP22 Same as above, with VER 1 MSNP22. The windows 8.0 messaging client uses this. No third party implementations I'm aware of.
