@kallekn @osma @pixelfed Over the past day or so, there's been a massive number of people migrating from Instagram to Pixelfed.social for Zuck-related reasons.
Earlier today, it was particularly bad, because many were trying to pull across their Instagram posts and videos at the same time.
You can probably imagine how thousands of people suddenly trying to upload hundreds of megabytes of photos and videos at the same time isn't great for server capacity.
@dansup temporarily switched off file migration and, at one point, federation to keep the site online.
It seems to have stabilised a little, but it's still intermittently patchy.
Most of the first-time users are signing up at the main instance, so Pixelfed.Social is likely to be a bit wobbly where other instances aren't.
Hopefully in the coming days, as more server capacity comes online, those issues settle down...
