[Operators] Some public XMPP services seems to not be available anymore

[naw]

Hello, some of the services in http://xmpp.org/services/ seem to not be available anymore, so maybe you will want to update the list.

jabber-hispano.org and lethyro.net domains doesn't resolve.

netmindz.net server seems to have been down for some time, although the web page is reachable ans list jabber/xmpp as a service, so maybe the server crashed and the admin didn't noticed.
