Description (last modified by chris) (diff)

The load on the live server today was such that it ended up in off-line mode.

It's now right down again, after these things were done:

  1. Munin has been stopped on kiwi, there are alternative stats here:
  2. "DTS Agent" (which appears to be a spam bot) was requesting a huge number of pages so it's been blocked at a varnish level following the suggestion here http://omninoggin.com/web-development/block-unwanted-spam-bots-using-varnish-vcl/
  3. We have increased the amount of CPU slices quince get's to address the steal issue show here https://ecodissident.net/munin/webarch.net/quince.webarch.net/cpu.html
