these are Fediverse instances my server has connectivity problems with.
exactly, delivery from my side does not work for (backward connectivity sometimes works fine):

blob.cat
eldritch.cafe
freespeech.group
friends.grishka.me
gnusocial.net
juick.com
loma.ml
social.inex.rocks
social.manalejandro.com
x0r.be
zotum.net

can't say why. I just see delivery errors in logs. maybe some network problems, maybe some protocol inconsistencies between platrorms/servers, maybe connectivity data is wrong in servers' public interfaces like webfinger, or something. just the fact.

at the moment, I have contacts that followed me on these servers and I'm pretty sure they can't read this post. as well as I cannot reach the admins of these servers because I get HTTP errors and/or other weird answers from their servers.
so I just make it public, pin the post and just leave it here. if you can see this post and see your server in the list, please check the connectivity to my server or ask your admins. if they blocked my address or something I want to know because I need to block them in turn to stop this strange and bothersome undelivered posts resend attempts on my side.

if you're an administrator of these servers and want to solve connectivity problems - I'm ready to get into details and see what's going on from logs on my side, etc. I'm programmer and I always stand for normal server interconnection.

some servers are banned on my side. I do this just in case a server breaks the network exchange rules, has spam/malware/porn content or has banned my server by some I-don't-really-care reasons to prevent the posts resend cycles. I'm not aggressive dork but roaches in somebody's heads are not my problem. I may dislike some users and I may block them but usually this does not come to blocking whole servers. blocking servers is stupid. but when I get blocked I have no other choice but block them in my turn because futile delivery attempts waste network traffic and CPU on my server. I don't see reasons for this.

some IPs may get banned on my side: if I see problems from some network address like ddos-like messages attacks, scraping, script bots, malicious behavior, attempts to break protocols, etc. I block such things without a special notes. I think Fediverse is not a place for spam and malicious attacks.
