IP connectivity problem debug request

As posted in #meta: https://wordpress.slack.com/archives/C02QB8GMM/p1670234270428419

I sorry if I chose wrong channel, but I’m having trouble accessing api.wordpress.org from multiple servers, like in these threads: https://make.wordpress.org/systems/2020/11/25/are-there-any-network-level-non-nginx/ https://wordpress.org/support/topic/server-ip-blocked/page/2/ https://wordpress.slack.com/archives/C02QB8GMM/p1605164522008700

For example I can resolve api.wordpress.org, ping it – but not connect to 80 or 443 port: https://pastebin.com/r1B4PvPg
tcptraceroute to 80 and 443 ports: https://pastebin.com/qyQid5aB
tcpdump, GMT+3 time: https://pastebin.com/Tzd3JPMR

From another server (IP, same /24 subnet) everything is fine: https://pastebin.com/sHuCRkvG
Or, if i add custom route for on the problem server, api becomes available: https://pastebin.com/1DnmeL1i , https://pastebin.com/hEKrWMwr

Looks like is banned on api.wordpress.orgWordPress.org The community site where WordPress code is created and shared by the users. This is where you can download the source code for WordPress core, plugins and themes as well as the central location for community conversations and organization. https://wordpress.org/ or something in beetwin blocking traffic from api.wordpress.or to Can anyone check this?

Can systems please check, and for future requests, state how they’d like these to be raised when they come in? I didn’t want to just tell them to email y’all without you expecting it.
