Update: (Sunday 23:00) And we're back. 2 million posts have been deleted, and their communities have been disabled in the bot. That should keep things going a little longer.
Update 2: (Monday 10:00) All the communities have been synchronized and are up to date again. That's great news! Before the purge it would take at least 24 hours to handle all communities after an outage, and even then it'd be lagging behind.
The bot is currently paused on account of a huge cleanup taking place.
The amount of post has once again outgrown the size of the server, so a lot of communities and posts will be purged, focusing first and foremost on those with the least amount of interaction.
The server had been running flawlessly for the past few months, but apparently we hit a bottleneck at around 7 million posts. Which is nothing to be sneered at.
Anyway, for the upcoming week or more, a huge cleanup action will take place (deleting nearly 2 million posts), during which the bot will not run. This should give some breathing space, and also slow down the growth going forward.
So for all the Lemmit users: sorry for the delay. Also sorry if your favorite community got wiped, and no, this is not negotiable.
