I see you're still on 1400. Let's go back to 1500, then move down until we find a happy place again.
Your issue is peculiar because I can send a 1500 byte frame through your line without issues. It's just when we inspect the packet in wireshark or the like, we see poorly reassembled packets every now and again. As though a switch, somewhere, is reassembling packets incorrectly. Saw something similar on an Octotel VLAN this week too. Without being able to directly log into the switches and check configs or run tests, we're at the FNO's mercy - which is an uphill battle.
Investigating further, it seems like the 195.66.227.209 hop belongs to AS6713 (Maroc Telecoms) - some sort of remote peering session from the DE-CIX exchange. Losses are happening on this hop (probably route congestion on their network). Our upstream are going to try adjust routes.
Ok, traffic's been re-routed and looking a lot clearer this end. Please check
Can you let me know which sites (on a ticket if you don't want to publish here).
Many different sites, posted a screenshot/example
Can't even access this from a Vodacom connection. Another one perhaps?
www.rt.com is another example
No issues opening that here - (testing from home on Vumatel). I see you're on 1500 MTU. Don't want to force a change this side and drop your traffic. When you get a chance, change to 1480- please test gaming once you do (I think last time you struggled with that).
Spoke too soon, www.rt.com not loading again

Try this site and see what MTU it suggests (icmp needs to be enabled in your firewall): http://www.letmecheck.it/mtu-test.php
Thanks! Worth a try- take your Router MTU back up to 1500 before running this test (don’t want artificial limits affecting results).
Ok, took it back to 1500, rant the test, it suggested 1440 now, so changed it to that but still can't load the website in question. IPv6 test failed completely though, the results are for IPv4

Sounds like possibly a firewall issue, i saw in one of your other posts you are running an MT router.
Do you have a rule at the top of your "Filter rules" to allow established and related connections?
Tried loading the page on two different browsers and on my phone via wifi, same result, just won't load. However, I can ping www.rt.com..... very strange
