Updating VSCode fails due to DNS SERVFAIL

[FomalhautWeisszwerg]

Does this issue occur when all extensions are disabled?: Yes/No

• VS Code Version:

$ code --version
1.105.1
7d842fb85a0275a4a8e4d7e040d2625abbf7f084
x64

• OS Version:

$ uname -v -m -o
#1 SMP PREEMPT_DYNAMIC Debian 6.16.12-1 (2025-10-13) x86_64 GNU/Linux

VSCode version and OS version might not be related to this issue. Because DNS name resolution fails.

Steps to Reproduce:

1. start nslookup in interactive mode.
2. set debug mode.
3. set server to 1.1.1.1 (public DNS resolver from Cloudflare)
4. try to resolve "packages.microsoft.com"

then get SERVFAIL like following

$ nslookup
> set debug
> server 1.1.1.1
Default server: 1.1.1.1
Address: 1.1.1.1#53
> packages.microsoft.com
;; Got SERVFAIL reply from 1.1.1.1
Server:         1.1.1.1
Address:        1.1.1.1#53

I think something is going on at Microsoft. About 15 minutes ago update.code.visualstudio.com had no DNS records, now it does.

I cannot download VSCode on a remote host via the remote-ssh plugin

It is not working to update in Visual Studio Code, also in Visual Studio Code Insider
