# DNS failures cause resolved to rotate to the next server. If StaleRetentionSec
|
|
# is 0 (the default), it then flushes its cache (in `link_set_dns_server`), thus
|
|
# causing more queries to hit upstream servers and risking more DNS failures.
|
|
#
|
|
# Synapse causes a lot of queries. By skipping flushing we actually get resolved
|
|
# to cache a meaningful amount of answers and drastically reduce the amount of
|
|
# failures Synapse encounters.
