[Koha] Slowness & outages

[Jason Boyer]

Hi Mark, while I would encourage you to keep looking into Anubis something
you can do to buy yourself some more time is to block user agents that are
almost certainly fake. One of your examples shows what claims to be MSIE 9
running on Windows CE. Actual patrons are not running anything with Windows
9X, NT 3/4/5, or CE, all of which you're likely to find single requests per
IP in your logs (and mostly wouldn't even be able connect to modern TLS).
Also blocking anything claiming to be Chrome or Firefox with a version less
than 100 (several years old by now) will make a huge difference without
actually impacting real users. Though that one may need to be narrowed down
to just Windows and macOS if you have some locations using old Linux
machines (usually Raspberry Pi's) running older versions of Chrome, because
it can't keep itself up to date as easily on Linux.
Good luck!

Jason
