for Venti, it is what I observed, for the servers, there are many articles including techcrunch published how roblox completely changed its tech stack which shows that roblox moved from cloud computing provider to own datacenters
For the hardware upgrade, not confirmed or anything but what is used is likely NAT, and a new switch providing hardware ddos mitigation. the switch is extremely expensive.
Why did you replace parts of the address with **#**s?
Since it could be anything, such as on one server I played it was 10.208.5.82 and the other was 10.208.7.21
Whats happened to Amsterdam servers?
Likely down for maintenance, I don’t see any games have it and it is impossible to ping the server, not sure about what happened.
I’ve been on the whitelist for a few months and none of my servers will form. It’s making my games 100% unplayable.
It’s likely the whitelist is strictly forcing datacenter 232 (the netherlands server) on your game, meaning if the netherlands server is down, it will try to form server on the specified datacenter but is unable to, I recommend contacting whoever gave you the whitelist for a timeline on how long the downtime will likely last, and creating a duplicate of the game to temporarily get rid of the whitelist
Update 3/15, Dallas servers now fully have protection.
I feel like significant areas should have DDoS protection, like Virginia. Virginia is a good spot since it covers most of the East coast
Amsterdam protected servers have returned. I see a couple of them on Deepwoken.
Is there a way to create servers that have only those IPs? I own a small game, having 1-3 servers is quite ideal and it would be even better if they were protected
You could, but someone need to create the server manually with vpn and check it manually, I don’t think there is an api to do it but I might be wrong
I just realized - I’ve kind of just been taking it at face value based off this post, but how do we know UDMUX servers actually have DDoS protection? I know the Roblox gamejoin endpoint gives an internal 10.x.x.x IP address when joining a game, which the game client then resolves a “UDMUX address” for to connect to. But how do we know anything more than that? I can’t find much other information on this.
It’s just based off my experience tbh, for the most part ddosers cannot hit servers with these ip addresses or can only create a small lag spike that lasts for less than a second, any youtube videos showcasing ddos tools avoids mentioning any of these server, pinging the ip address doesn’t work either, guess we’ll never really know what goes on with the server since it would defeats the purpose
and im pretty certain at one point, like any security measures, will be bypassed
(or this whole thing could have just been unintentional)
You should consider updating this.
Roblox recently added udmux to UK servers, Well as far as i’m aware they haven’t really added it but instead they added Paris’s protection to British servers, when I joined a game with the region London for example and that I looked into the network the end of the UK server’s IP had .33
PSA : Games are still at risk of getting ddosed even with udmux.
and is almost every other server (except japan and DC for now), problem is, people has found a bypass and came back to ddosing, and developer afaik can do nothing about it except locking the server list behind a wall through reserved servers
The bypass has been up for years now, I mean nothing is protectable nowdays am i not right? but one thing for sure is the packets sent are LESS huge and it can sometimes freeze 2 seconds then go back to normal which is kinda formidable compared to a full crash…
who do i have to sacrifice to get roblox to build UK servers so i can get less than 200ms ping 
(disclaimer: I do not know what I am doing but according to a traceroute i’m bouncing through hull, manchester, slough, london, paris & frankfurt)
How can I do that? Anyone can help me?
you have to use a VPN, or travel to that city haha
