I've noticed that the external communities I'm subscribed to aren't syncing. I checked a few on their home server (lemmy. world), and they've got plenty of new posts (eg. !news@lemmy.world), but the posts aren't showing up here. I don't think it's just me, but I've been wrong before. Anybody else?
nameservers and some of the access to the servers got messed up. Server couldnt see anything outside of programming.dev due to the nameserver not working
I came here because I noticed I wasn't getting the posts from here on Mastodon anymore, since sometime a day ago (newest post in my Mastodon "Programming.dev" List says 1 day old). Sounds like the same issue, but thought I'd add this info as all the other comments are about not getting posts from other places here, but I'm not getting posts from here at Mastodon.
It seems that something went wrong with our nameserver, thus no connections to the 'outside world' were working. As soon as I added a new nameserver, federation started working again (this also affected server updates).
It seems that something went wrong with our nameservers, resulting in an inability with the instance to communicate with the 'outside world'. I'm not really sure how that happened, but I added a different nameserver and federation started working again immediately.
