kɜ:ʳ @chr@cybre.space

hey y'all, i'm no longer reachable on discord if you had my info there previously. if you need to get in contact with me, i'm @chr:cybre.space on matrix, @chr1x on wire, or you can email me at chr@cybre.space (or admin@cybre.space if you want to reach @nightpool as well)

hi i'm chr and its my life mission to boost every dragon

got quite a few new folks here today, welcome! your admins here at cybre.space are myself and @nightpool, you can read the instance rules at http://cybre.space/about/more, and likes ⭐ are florps here. if you have any questions, feel free to ask! happy pinging!

the ghost in the machine sounds like a pretty spooky guy

the internet had our old phone number, i'm trying to give it the new one but it takes a really long time to write it down

decided to move off of cloudflare DNS due to centralization and single point of failure concerns, as well as minor privacy concerns

we used to use our own DNS server, which worked fine, but while we were on cloudflare i moved that DNS server to a new host (with a new IP) and forgot to update the glue records

so the glue records are pointing at the old IP, which means that until the .SPACE authority's cache is refreshed, DNS queries for cybre.space and subdomains will have a bootstrapping problem and be unable to resolve

...i may have spoke too soon

depending on your dns caching settings cybre.space might have been unavailable there for a little bit

if it wasn't, don't worry about it

if it was, i think i fixed it

phew

hey anyone who uses Matrix through the cybre.space homeserver from the web client (https://matrix.cybre.space), heads up that we just upgraded to the latest version of Riot where they rebranded as Element. it's the same thing as Riot, just with a different name (they wanted to be able to trademark the name to prevent use by bad actors).

so other than the name and icon (and some minor UI changes) Element is Riot. nothing else changed.

netdata on the cybrespace matrix server has been reporting the following alarm at a steadily increasing rate over the last couple months: ip.tcp_accept_queue, "the average number of times the TCP accept queue of the kernel overflown, during the last minute"

this seems like the symptom of another problem, but i can't find much information about what it might be a symptom *of* (other than, possibly, a slow application not accepting connections fast enough).

can anyone advise? what should i be looking for to further diagnose the cause? what, if anything, could i do to mitigate this at the system level?

cybre.space users: apologies for recent federation delays, it seems during times of peak activity we've outgrown the number of sidekiq workers we've been using. i've scaled them up and hopefully the instance will perform better under load, but i'll be keeping an eye on things over the next few days to be sure.

cybre.space users: general reminder, please don't post screenshots of posts from users on other instances. mastodon doesn't have quote-posts for a reason.

periodic reminder that we run a matrix instance at https://matrix.cybre.space/

matrix is a modern (federated!) chat protocol with all the bells and whistles -- look for Riot in your favorite app repository / marketplace for a slick client that can connect to any matrix server

or you can use it on the web directly at https://matrix.cybre.space/

(join #meta:cybre.space if you're interested in discussion and updates about this instance and our matrix server)

okay, local folks: images should be back if you refresh the page

something's going wrong with the custom domain feature of digital ocean's CDN. it will serve images successfully if you query it directly, but not if queried via a CNAME (domain alias), which we use to point https://dostatic.cybre.space to digital ocean's endpoint

i'm going to file a ticket with digital ocean and change cybre.space's server configuration to use the CDN endpoint directly instead of via cname for the time being.

cybrespace image outage appears to be a problem with our media provider, digital ocean. more details as i investigate further.
