Slrpnk instance is down till mid July; they might relaunch their server on piefed.

Our sysadmin explained some technical advantages here: https://feddit.org/post/13613230/7063696
Postgres slowing factor
I'm pretty sure one of the best optimised free/libre DBMS's is faster than Python
EDIT: skimmed it wrongly, see corrections below
Also no one know how Piefed scales, since it only has like 350 MAU

Piefed also uses PostgreSQL. He was mentioning that the limiting factor on either platform is the DB, meaning that the parts written in Python will likely not be a limiting factor.
Piefed also has quite impressive optimizations in other areas as well compared to Lemmy or even Mbin.

well that's poor planning and why bots are such a problem.
I know CSRF tokens aren't a silver bullet, but doing nothing to stop them does nothing to stop them.
CSRF protection is a security feature not bot prevention. A bot would just need to get a token first.

Reread it. They're saying "The slowest part is postgres, so even if python is slower than rust it won't make a difference."

XKCD #2347
Ya gotta give a line from it or something, I don't just see numbers and know what they are.

Did they run out of sun?
No, just punk.

After a month and a half downtime all the users will have moved on to other instances. This is essentially a death sentence for the instance and its communities.
I don't think so, I will definitely go back and do not wish to move permanently in another instance.
As others have said I think this instance has a strong base of dedicated users, it's a "specialized" instance that has no equivalent.

from context, it's probably the "single dude in nebraska holding up the entire internet" one
e: holy shit I got the state right

Slrpnk.net admin here.
The failure seems to have been in the main firewall, if it had been the server itself we could have easily restored it on another server from the backups on another machine. But as it stands, remote access is entirely cut off.
There usually is another person with hardware access, but they are on summer holidays. This seemed like an acceptable risk at the time...
An off-site backup would have been nice of course, but due to the costs involved in running an Lemmy instance of that size on a rented server, it would have not been a great option either.
I have plans to add a KVM to the main firewall via a secondary connection, but even that might have not helped in this case. I'll know more when I have physical access again.
Is it run out of a private residence? How could it happen if it’s in a real data center…?

It is run from a private residence in the DIY punk spririt (and this also allows us to run of a local solar PV system), but more or less the same would happen if you rent rack-space in a "real" data-center. Only if you rent a managed server or VPS someone else will be responsible to fix such issue and this comes at a significantly higher cost at the scale we operate at (slrpnk is part of a bigger project that also hosts other services).

If you rent rack space, you can at least call the DC to send someone to reboot it or smt.

That is, in theory. In practice, it can make a big difference. Source: Worked professionally with large services built in Python and Rust.

Sure, but they will not replace hardware and set up remote access for you, which seems like this would have been required in this case.

What is so special about piefed? I see a few communities moving there. The interface looks different from the original lemmy interface.
For regular users there is not a huge difference, but the web-interface is significantly faster and you can subscribe to topics that combine multiple communities. The disadvantage is less mobile app support. Right now only Interstellar supports Piefed.
The real advantage is for moderators and admins, as the Piefed developers actually listened to community feedback and implemented a lot of nice moderation features that require bots or annoying work-arounds on Lemmy.
And there are a few technical differences that make Piefed easier to administrate and troubleshoot from a sysadmin perspective.

Yes, I also suspect that at a certain scale it would make a difference, but with a single Postgres database and no advanced clustering or so, the real-life performance metrics of a medium sized Lemmy instance strongly point to Postgres being the bottleneck and not the Python or Rust codebase of the rest of the software.

"unforseen hardware failure"
somebody didn't check their backups!
