900Mb internet speed.
Need I say more? 
Because the VPN “remedy” is an utter nonsense. Asobo/MS have already stated that the cause appears to be due to the way the software processes the data it downloads. Nothing to do with VPN speeds.
Hopefully FS2024 will be better as it, or so we’re told. is built differently. I’ll hold off from buying FS2024 until I can see that the download speeds are improved. Oh and that PMDG B737 series will work on it. PMDG have already stated that they are unsure as yet as to how much work will be involved in making their B737 aircraft FS2024 ready.
This is me trying to dl updates. I have a 500mbit connection and the content manager of MS Flight Sim is the ONLY place this is happening.
It’s clearly not. If it was the VPN would make no difference, and I have used Proton in the past, and seen huge changes in download speeds, but it’s very situational.
All it is doing is giving you some small degree of control on which CDN servers you are connecting to, based on the exit point of your VPN.
If it were just a client side issue, as you seem to suggest, then why did they throttle downloads to 1/8th of what they were, on the server side, to allow more users to download SU13/SU14 at slower speeds, then reverted the changes once it was seen most of the backlog had cleared?
This is not a client side issue, but a server side capacity issue, and the VPN merely gives you some scope over what you are connecting to from a geographic standpoint. You might be lucky, and land on one offering good speeds, or you might not.

Oh guys, i downloaded almost everything with that turtle speed, now only 3 last world updates left.
But DL speed is now like 0.50-0.90 Mbits, so its killing me.
Im sad becouse it works normally for some people, maybe it depends from where You are DL.
Im based in Poland , Europe maybe thats the case. But on the other hand DL speed sometimes reach normal 250Mbits per sec, so im going crazy why it doesn’t hold that or similar value most of the time.
I have real fast internet , good pc and clean hardware. I tried that VPN solution but with no luck.
Gonna restart PC and see if that helps.
I have a 1gb connection and downloads are very very slow.
Hi, well I do have a paid version of ProtonVPN. I just select USA as a server and that’s it.
Im devastated, but i made a progress, now im waiting till last world update gets downloaded. It is still around 2-3Mbits per sec, with optional up to 250Mbits from time to time. It is progressing. Hell, i t was long 12 hours and now at least 2 more.
Thank You for answer PHP, i tried Proton VPN but with no any luck, even ifi switched to few USA servers my download speed stays the same.
This is just as baad as the last times there was an update/new dl.
Getting fluctuating between 0.1 - 3 Mbits(s
MS please get this fixed, is getting getting pretty annying.
From Denmark on the western europe server.
Just installed Proton VPN and choose a location where it’s currently in the middle of the night (less network saturation).
Results: Download speeds increased from a crawling 0-1 Mbps to a whooping 130 Mbps.

Switched to a US server on my VPN and got better speeds so there is some stupid throttling going on in EU.

Where is the server you chose? I had tried NYC with Surfshark and it didn’t help at all.
exactally this, it may be worse and affecting more people now, but some had this issue pretty much since launch

In the January Dev Livestream, they said that they are aware of a problem of cache of their CDN provider (PlayFab), but the person that asked the questions of slow download speed was refering to the content manager downloads if I can remember well. Anyway, the issue is the same, I hope that it’s gonna be fixed finally.
I can’t imagine spending 2 days of downloads for MSFS2024 if it’s like 400Gb of download, at a speed of 2Mbit/s 
I am currently trying to download that new Dune plane. 4.52 GB download, has been going for 1.5 hours now (gigabit internet). This is ridiculous, very sad and angering that they think that the quality of this service is enough.
It clearly is, judging by what MS/Asobo themselves said.
They also said they had fixed it, which they clearly haven’t, so…
If you use a VPN, and land on the right CDN server you will see better speeds. If it was just a client side issue the VPN would make no difference, but a lot of users report that it does, including myself.
It’s not a magical fix. Sometimes it makes no, or little difference, but others you can go from 2Mbps, to over 200Mbps.
Plus, look at the incident report where they wrote about the issues with SU13, and SU14 downloads. At no point did they mention it was a client side issue, and all the mitigations, and tweaks they made were all server side.
I’m just looking for a link to that text…have a look at the post incident report. There was a bug on the server side, issues with SAS token generation, and they ended up throttling users to 1/8th of normal parallel connections.
After all that, their impression is that everything has returned to normal. And here we are with 2Mbps download speeds >90% of the time.

My impression is the sim is a victim of its own success. At least for the launch days there are simply too many clients connecting at the same time.
As you say, I’ve used many different DRM systems, from Valve, Ubisoft, EA, GoG, countless MMO’s, and none of them have been plagued with issues like this.
When I raised a question about this on the PlayFab support site, it was never published, and deemed “inappropriate”.
If I had to guess, this is an internal corporate thing. Kind of like where one department will bill another, the MSFS team may not be able to request/demand additional capacity in Azure, and we are all fighting over the scraps of what is available. 
I have no horse in this race, so happy to be proven wrong, but I’ll eat the hat I don’t own if they fix this with a client update.

That’s what I find so frustrating about all this.

What I found frustrating is that I can’t understand why MS won’t sack this CDN provider, if they clearly not providing a sufficient service.
