Yes, I see a big drop in EXP volume starting yesterday, December 17, around
14 UTC.

Something of interest that may or may not have any bearing on your
ingest is the result of doing DNS lookups for your machine:

:~$ nslookup ldm-wxo.cmc.ec.gc.ca
Server:         127.0.1.1
Address:        127.0.1.1#53

Non-authoritative answer:
Name:   ldm-wxo.cmc.ec.gc.ca
Address: 205.189.10.53

:~$ nslookup 205.189.10.53
Server:         127.0.1.1
Address:        127.0.1.1#53

Non-authoritative answer:
53.10.189.205.in-addr.arpa      name = ldm.weatheroffice.ec.gc.ca.
53.10.189.205.in-addr.arpa      name = ldm-wxo.cmc.ec.gc.ca.

Authoritative answers can be found from:

You can see that the name ldm-wxo.cmc.ec.gc.ca resolves to the IP
address 205.189.10.53, but the IP address 205.189.10.53 resolves
to two different names:

ldm.weatheroffice.ec.gc.ca
ldm-wxo.cmc.ec.gc.ca

Since ALLOW actions are typically specified by fully qualified
name, it may be the case that one or more of the upstream sites
that you are REQUESTing an EXP feed from has an ALLOW specifically
for the ldm-wxo.cmc.ec.gc.ca name and not ldm.weatheroffice.ec.gc.ca.

re:
> Can you confirm our new servers our working correctly?

There is not enough information to make any sort of a comment wrt how well
your system is working.

What we need to know is:

- from which upstream site(s) are you requesting EXP data?

  Please send us the REQUEST line(s) for EXP from your LDM
  configuration file, ~ldm/etc/ldmd.conf

- if your LDM is REQUESTing EXP from more than one upstream
  site, did you notify all of the sites about the change to
  your machine?

Cheers,

Tom
