The database migrations took a while which meant about 10 minutes of downtime between 9:09pm and 9:19pm NZT. But the site is now up and hopefully running OK. Let me know if you see any issues. I'm hoping this will lead to a more stable site, but one big issue still hasn't been resolved so I can't promise anything.

And since we're doing an announcement post, here's a couple of things to check out that I never officially announced:

  • Voyager (previously called wefwef) is a web app for Lemmy intended to resemble the Apollo reddit app. You can use any instance but we have our own hosted at voyager.lemmy.nz

  • mlmym is an alternate frontend intended to resemble the old reddit theme. As far as I can tell, this is specific to an instance, so will only work for people with a lemmy.nz account (but other instances have their own version, such as lemmy.world). You can access this frontend at old.lemmy.nz

These are both set to auto-update, so please let me know if an update breaks things because I can roll back to a previous version manually.

Nice! Will be interesting to see a graph of server load & database size etc. to see the impact of the changes

[–] Dave@lemmy.nz 3 points 1 year ago

Right! Here is the load over the past day an a half or so. It graphs the average every 30 mins:

This one shows the same thing but with maximum load over the 30 minute slots:

The peaks between 1am and 4am are parts of the backup process happening.

The upgrade was done at 9:09 last night. It looks like there might be a difference but perhaps we need a bit more time to see the average.

This would have been easier if I had thought of it beforehand 😀

@idanoo@lemmy.nz I can only see the last hour's stats in proxmox, is that all it's saving or are you able to go back further and show the before/after CPU load (the update happened just after 9pm tonight)?

Indeed it is; I'm also registered at another instance and if I put "old" before the URL, it won't load. Also, thanks!

[–] Dave@lemmy.nz 2 points 1 year ago (1 children)

What I meant by that is that, as an example, Voyager lets you type in which instance you want to conmect to. So even if your account isn't on lemmy.nz, you can still go to voyager.lemmy.nz and log in using your account.

However, for old.lemmy.nz I don't think this is an option. I think it will only work for people with a lemmy.nz account.

I'm on desktop / Firefox ESR and don't use an app, but can access old.lemmy.nz either way -- whether signed in or not.

old.feddit.nl will not work at all, whether I'm signed in or not, because the admin is not (yet) using mlmym.

As a workaround, I have to go to https://mlmym.org and enter feddit.nl in the box.

[–] Dave@lemmy.nz 1 points 1 year ago

Yes, that's expected, as mlmym is separate to lemmy. I'm not sure I quite got my point across but it doesn't matter, I think you understand what does/doesn't work.

Nice... finally hot sorting is working as designed!

Thanks Dave!

Is there a way we can contribute to the running of the server/s. If it be in the form of admin - pull requests etc. or Financial?

[–] Dave@lemmy.nz 3 points 1 year ago (1 children)

Lemmy.nz runs the Lemmy software. They absolutely take pull requests if you're familiar with the technology, check out: https://github.com/LemmyNet

The code is across multiple repos, the main ones would be "lemmy", the backend, and "lemmy-ui", the front-end website.

The lemmy.nz server is being hosted by (but is not run by) fediservices.nz, and you can donate to them to help with server costs: https://opencollective.com/nz-federated-services

awesome thanks I didn't know about fedizservices.nz sounds like a good cause.
