Seriously, what is going on at GOG that downloads are slower than snails? For the past couple weeks now download speeds have been below 100Kb/s. It is definitely not my Internet, I can download from Steam just fine, it is only GOG. I have been working on downloading Fallout 4 for over a week now!!! but each 4gb file takes 12+ HOURS!!!! to download. It does not matter what time of day, it is always extremely slow.

I have been with GOG since the beginning and have never experienced such horrible download speeds. Is GOG on its last legs? Do I need to find a way of getting all my stuff downloaded before GOG shuts its doors for good? What is the deal?

Extremely frustrated

Are you using a web browser or Galaxy? Browser downloads are slow, Galaxy is a bit faster, if inconsistent. You can download offline installers through Galaxy, so I would recommend trying that. Also means you don't have to individually download 12+ files.

For comparison I get download speeds of 100kbs - 300kbs in a browser, and between 1.2mbs and 10mbs in Galaxy, with it usually settling in around 3mbs.

For me, this has been the norm ever since the migration from their previous CDN (Lumen/footprint.net) to the current (Fastly). Fastly does not have a terrible reputation; so, I wonder if GOG is simply paying for one of the lowest tiers...

Also, not that it should affect download speeds (only adds slight latency), but, with Fastly, I am always downloading from one of their servers that is quite distant in relation to my current position, while a server in [insert one of the largest U.S. cities] would be the more logical choice.

There seem to be a fair number of such complaints recently, wonder how a map of the users who experience these problems would look because it may be either a CDN issue or something unrelated to GOG at all, but to some Internet nodes.

Tested and I'm getting 5-6 MB/s just now from GOG, quite normal. But for the past several days there have been some sites that I regularly use but which now barely load or time out altogether, which is what made me think about that possible nodes issue. May be worth checking if there are any other sites with servers in the same area as GOG's that you have problems with, though that is likely quite hard for a regular user to figure out.

Pretty fast download speed here... 4x4 GB files are downloaded in a few min, at least for the huge games. Some small games seems to be slower... but it will not take forever, for me.

I get a stable 50~60MB/s here, using LGOGDownloader.

From what I gather from the previous discussions on this topic, this varies a lot based on your location.

I am using a browser. Just tried to start it in Galaxy, and it is barely any better 0.3mb/s. So Galaxy is not the answer. GOG has a serious problem that they need to address.

Just to confirm some others that this seems to be a regional thing, or at least doesn't affect all users.

Just to test, I am now downloading Pillars of Eternity offline installer with the EDGE browser (Windows 10) at around 24 MBytes/sec (= 192 Mbits/sec). That is fast enough for me, even if in theory my cable modem theoretical max limit is 600 Mbits/sec (but there are other users all the time here too using the same connection, so...).

I haven't really noticed that sometimes it would be faster and sometimes considerably lower, I seem to be getting such "good enough" download speeds every time. HOWEVER, I think I did notice I also get even faster download speeds by using the Galaxy client (even to download the offline installers), so it might make sense to try it out as well.

At the moment the main complaints seem to come from Australian and US users, not sure how widespread it is in those regions. Some have reported they get considerably better download speeds if they use VPN to lie to GOG they are on some other region. Maybe you should try what you get if you use VPN via Finland? :)

While this will not fix your problem, this way you can check the location of the (possibly problematic) server that you are downloading from when using the web browser (not Galaxy):

1. In the Windows command prompt, type:

nslookup gog-cdn-fastly.gog.com

That gives you an IP address on the "Address"-line. Something like 155.111.243.57 (not a real example).

2. Check the location of that IP address at https://www.ipaddress.com/ip-lookup
Type the IP address to the search box, and click the "Lookup" button.

In my case I seem to get a nearby server in my country, so I guess I am lucky.

Apparently here are all the different Fastly CDN servers around the world, but I have no idea if GOG uses all of them or only some of them:

https://www.fastly.com/network-map/

I agree, something is up. Speeds were ok yesterday, but today they are less than 1/10 of what they were yesterday. Hopefully it is resolved sooner than later.
Good idea and I appreciate the write up. My Fastly from GOG is in Montreal, so I set my VPN (PIA) to Montreal. Unfortunately it made no difference. When I get more time later today I will try other locations. Thanks again for the post, at least I learned something.

Well, there wouldn't be any difference if you're still using the same server (or, if anything, going through a VPN may make it even slower). The question is what happens if you use a VPN to force GOG to assign you to a server that other users confirmed offers high download speeds. If the problem goes away, it means it's caused by a certain server used by GOG. If it doesn't, it likely means it's closer to you than to GOG, maybe even having to do with your ISP.

I noticed a tremendous drop in download speeds the last few months. I'm downloading games now one at a time and a 3GB game has taken 20 minutes. previously, a game of that size took a minute or less.

I did notice several such forum posts and yes i also have slower speeds than usual since i get maxium 4mb per second instead of 24 or somewhere over 20 megabytes per second.
The summer CDN outage and gog claiming to they fixed it but maybe this is why we get lower speeds.
Won't download bigger games until the speed is fixed if possible.
But i do wonder did anyone write a support ticket to gog about this issue yet?
Why is Clownski quiet when it comes to this issue is it because it was already mentioned?
Also i wanted to backup the last few missing games, but i can't and won't until this speed issue gets fixed since i got the 5tb external HDD for this time but then the summer CDN outage happened when i got my HDD
Only use win 10 and edge browser and used to download offline installers.

GoG generally is pretty scarce when it comes to "handing out information", however, i think this whole server management is not entirely under their control as it is handled by some external storage provider. In this term such issues are not easy to be tracked down and most likely they even lack people...

I think GoG works alright if you are in a location with a certain server-standard, but if you are in a location with many "bad offers and a generally low standard" it may not become tasty, as GoG is not always using the "first class service". Alternate solutions are not always "up to the task".

I also noticed that GoG is using some better solutions for certain "huge games", while many of the smaller games may not get the best options and in this case with a generally slower download. So you can surely say, GoG is a bit a hit and miss here but i think in the US with a strong backbone, there is close to no bad servers... the only issue is still "the last mile" there... directly at someones home. Almost same for central europe (my location)... but if you are a bit outside (Croatia or Slovenia for example) it could become a issue.

By any chance you are using a third-party tool to change your IP address? This can often result in poor internet speeds, that is if you have opt for an unreliable tool.
The other possible reason could that you are not using the ideal internet browser. I have personally found Google Chrome or Mozilla Firefox to be the ideal candidates
