These pubs you mentioned are suffering under the large amount of traffic generated by HN and they were not designed for this load. Ideally hosting your own pub should be as easy as possible. My goal is to have it possible under a Heroku "Click to deploy" button or Zeit `now staltz/easy-ssb-pub` so that we can have more pubs. By the way, my pubs are public just because I chose to, but I may take that down if I want. No data would be destroyed, since you'd have all that locally and you can connect to any other pub and replicate through that.
All pubs on the wiki are indeed overloaded. Interestingly if one sets up their own, the other pubs eventually sync with it, only the desktop client seems to be unhappy with laggy pubs. Is that by design?
FWIW, you can use pub.lua.cz:8008:@xYSW6eVu8gTS/nTSXZiH97dgKZ+wp7NkomR6WKK/PBI=.ed25519~iQ16RuvjKZqy/RhiXXmW9+6wuZNq+SBI8evG3PotxvI= if you have trouble connecting to the ones on github.
Feel free to add it to the wiki, I do plan to run it long term, but I am not a github user.
