Downtime for Lemmy.nz this Friday (again) to move to a new VPS (lemmy.nz)

Earlier in the series:

I have an update in this post. TL;DR we are losing our host and will need to move to a VPS.
We moved to object storage for images over last weekend.

TL;DR of this post:

We will move to a new VPS this weekend
Lemmy.nz will be down (properly down) from sometime after 7:30PM Friday until the job is done. This should be completed within a few hours but I reserve the right to use Saturday as well 🙂
Initial estimates are that the VPS will be around NZD $50/mo, on top of image storage costs (hard to guess - perhaps $10/mo)

I have now confirmed a plan with a VPS host Zappie, in their Auckland data centre. This is in fact the same place the existing server is colocated.

The specs of the new VPS:

CPU: 4 Cores Ram: 8GB Disk: 150GB Monthly Traffic: 1TB

We may need to adjust things as we go. Initially I will keep our current setup (including Cloudflare), but as we understand better what our needs are I am keen to move off Cloudflare as there was quite a lot of support for that move.

I have copied things across to test and it runs Lemmy well, similar to the current server, though that's without users, federation, and rogue AI scrapers but Zappie can bump specs pretty quick if needed.

Please let me know if you have any questions, I'm always happy to provide more details 🙂

Well the current server has 8 cores and 16GB RAM allocated, but now we have to pay for it I don't think we can justify all that power that doesn't get used. The CPU usage hovers around 10-15% most of the time, and the majority of the RAM use is cache.

If it's not powerful enough they can bump the specs up pretty quickly, but I think it will be fine. A service like lemmy is mostly database heavy, lots of writes with all the federation, but postgres handles this pretty nicely. It's only when AI scrapers get through that it struggles, and I'm going to look at putting Anubis in place to help with that. Currently I manually add ASNs (kind of like a grouping of IP addresses) to Cloudflare to send them a capcha based on high frequency IP addresses from problematic countries, but over time I'll work on reducing our reliance on Cloudflare.
