MAAS region controller has a local NTP server with "tos orphan 8".

In my case, I have only one NTP server with stratum=11 in reachable networks, so I set it as an upstream NTP server for MAAS. However, ntpd in MAAS does not sync with the upstream server.
$ ntpq -pn
remote refid st t when poll reach delay offset jitter
==============================================================================
<IP address of an upstream> LOCAL(0) 11 u 25 64 377 0.721 -799.12 2.326
When manually editing /etc/ntp/maas.conf with "tos orphan 12" and restarting ntpd, it's synced as expected (with "*" in front of an upstream NTP server).
$ ntpq -pn
remote refid st t when poll reach delay offset jitter
==============================================================================
*<IP address of an upstream> LOCAL(0) 11 u 30 64 377 0.640 -5.127 0.825
Acting as stratum=8 NTP as MAAS is a bit too much in some cases.
Could you try using the `fudge` command?
For example, to /etc/ntp.conf add:
fudge <ip-of-
and restart ntpd.
This should, I believe, make ntpd act as if the upstream server is stratum 4 instead of whatever it advertises itself at. See http://
