OpenWrt wiki down

The OpenWrt wiki is currently down. It stopped responding due to MySQL being overloaded. Since there was downtime already, this seemed like a good time for some maintenance.

Will post back when it's back up and running.

[UPDATE 00:15 CEST] the Wiki should be back. ToH is currently not working.
[UPDATE 02:35 CEST] ToH still not working. Someone who knows this part of the Wiki should have a look. If we can't figure it out within reasonable time, we'll revert to the snapshot taken right before the maintenance.
[UPDATE 11:35 CEST] ToH working again, performance tweaked. If anything is still broken, don't hesitate to reach out.
