Weird Google Issue for the Past Few Days
I've had intermittent outages for Google services including their search page, YouTube, Google Notes, DNS and others.
I set up a EMCO Ping Monitor today to track the problem.
I have pings to 1.1.1.1, 192.168.1.1 (my gateway), 208.67.222.222, 8.8.8.8, bing.com and google.com.
All have 100% uptime over the course of the whole day today except google.com.
It's uptime is currently 60.98%
And from the random Google searches and YouTube access, etc. I've done today that seems accurate.
Also, this issue is not on 1 computer only.
I've restarted my modem and firewall (pfSense) and went over all settings I could think of.
Nothing in my network configuration has changed before this started happening.
I suspect a routing issue on the Xfinity network near my home.
Any ideas?
EDIT:
I forgot to mention that if I start a ping from the command line to 8.8.8.8 during one of the outages it does not go through.
Also once a YouTube video starts playing it is not interrupted.
EDIT2:
Using ProtonVPN on one of my PCs seems to resolve the issue.
Edit3:
Set up a WireGuard connection to ProtonVPN on my firewall so all of my devices can use it.
Everything is working properly now.
Edit4:
I believe the problem may be a result of packet fragmentation.
I found that on my normal Xfinity connection I could ping up to 1416 packet size.
On the VPN I can ping with a larger packet size.
I've set my router's WAN interface MTU to 1444 and things seem to be running okay now without the VPN connection.
I do not know why this has just become an issue recently. The only thing I can think of is something has changed on the Xfinity network.
Edit5:
Posted too soon. Still having intermittent issues with Google services.

I think I may have solved my issue.
I rebooted my Motorola SB6120 modem (not rented) and it was not getting back online.
It kept rebooting during the last initialization step.
I found a post online of someone mentioning that they had to "reactivate" their modem on the Xfinity network and they were having similar issues to me with intermittent outages.
So I used the Xfinity app on my phone to reactivate my modem. The first time it didn't work. (I couldn't even access the modem's web portal and it just kept rebooting)
So I tried again but this time I chose Arris as the make instead of Motorola. The branding on the modem itself is Motorola but on the modem's web portal it says Arris.
Anyway after doing this a second (or third time? I can't remember) it rebooted multiple times but eventually started working.
It has been hours since then and I have not had a problem yet. The ping tests are solid so far.
I think Xfinity had done upgrades in my area recently and informed me of increased speeds. I'm assuming new equipment was installed and perhaps my modem's MAC was not populated to all equipment or otherwise not properly registered.
I really hope this is resolved now but if not I will post back here again with more information.
Thanks for the replies and suggestions.

Hey there user_8b3c07 is the 60.98% drop happening on all ping hops you've tested? You mentioned this is still ongoing - is that with WireGuard and Proton VPN still active? Or is this only happening without the VPN active?
