+# Note to self: A domain that cannot be resolved will cause
+# TRANSIENT_ERROR instead of ERROR, and the JobError notification will
+# not be triggered! This can bite you during testing depending on how
+# your DNS is configured. For example, if you use OpenDNS.org's DNS
+# servers, an invalid hostname will *always* be resolved (they
+# redirect you to a search page), so be careful when testing.
