Can't connect to internet on switch to testing repo

Today I attempted to switch to the testing repos. Before switching, I performed a full system upgrade. Then I rebooted, made sure everything was working then switched to testing. On the switch, I upgraded the following packages:

binutils-2.28.0-3  blas-3.7.0-2  cblas-3.7.0-2  diffutils-3.6-1  file-5.31-1  fsharp-4.1.18-1  gcc-libs-multilib-7.1.1-2  gcc-multilib-7.1.1-2
glibc-2.25-2  krb5-1.15.1-1  lapack-3.7.0-2  lib32-gcc-libs-7.1.1-2  lib32-glibc-2.25-2  lib32-libdrm-2.4.81-1  lib32-libelf-0.169-1  lib32-libltdl-2.4.6-8
libdrm-2.4.81-1  libelf-0.169-1  libsystemd-233-4  libtool-2.4.6-8  libwbclient-4.6.3-1  pango-1.40.6+9+g92cc73c8-1  smbclient-4.6.3-1
systemd-233-4  systemd-sysvcompat-233-4

Upon reboot, I was unable to connect to the Internet via ethernet. I checked the status of the dhcpcd daemon, and that was running just fine. I was able to connect within my LAN, pinging other machines and load a web app on my home web server. However, I couldn't connect to the Internet outside of my LAN. I downgraded out of the testing repo shortly after.

Any ideas on where I can start looking to diagnose the problem? I'm not sure what packages could be causing the issue.

Try pinging by address, such as 138.201.81.199, an Arch Linux server.
I assume this is a wired LAN and the only networking service that is enabled is dhcpcd.service.

I was able to ping that by address. Likely a DNS issue?

Yes.  Sadly, DNS is not one of my strong points.  We do know that drivers and stuff are all working.

libsystemd-233-4 systemd-233-4  systemd-sysvcompat-233-4

core has systemd 232-8 , and some systemd parts play a big role in dns resolving.

I suggest checking systemd changelog if you want to investigate further.

Multi-init booting with apg Openrc and systemd coexisting
Automounting : not needed, i prefer pmount
Aur helpers : makepkg + my own local repo === rarely need them

Re: Can't connect to internet on switch to testing repo

For what it's worth, it looks like there are a couple of systemd upstream bug reports out by Arch users that seem related to my issue:

#5782
#5915

However, these were first reported on version 232, while the testing repo is on systemd 233-4.

Here's /etc/nsswitch.conf (it was not changed when switching to the testing version of systemd):

# Begin /etc/nsswitch.conf

passwd: compat mymachines systemd
group: compat mymachines systemd
shadow: compat

publickey: files

hosts: files mymachines resolve mdns_minimal [NOTFOUND=return] [!UNAVAIL=return] dns myhostname
networks: files

protocols: files
services: files
ethers: files
rpc: files

netgroup: files

# End /etc/nsswitch.conf
