So Razor differs from DCC in that respect.
Razor and DCC differ quite a bit when you get into the details. Particularly now that razor has the e8 algorithm, which is more like SURBL than it is like DCC.
I gave up on Razor long ago due to delays due to slow Razor response, and repeated Razor outages. Is it more reliable today?
Yes, but DCC is still more reliable and faster. (I use both)
Late last week one of the servers dropped off, but before that it was several months since the last outage that was long enough for me to notice.
I'd recommend keeping your razor_timeout low if delays are painful to your server, but razor is a worthwhile tool.
I'd also consider shortening the rediscovery_wait a bit from the two-day default to one-day or so. Usually outages are corrected if you run a discover, since the cloudmark crew tends to update the server list when one drops off.
