Blackbox : 2 vCPU / 4 GB / 50 GB NVMe, Encrypted RAM & Disk, 100% Anonymous - $9.99/mo

servury · 7:24AM

Matteo again, from Servury. Two weeks ago I posted Blackbox, the VPS whose operator cannot read its memory, cannot read its disk, and cannot run commands inside it. Thread here. Since then we shipped the things people in that thread asked about, and re-specced the entry plan.

What changed since the last thread

Core is now 2 vCPU / 4 GB / 50 GB NVMe, same $9.99. The 1 vCPU / 512 MB Core is gone. If you bought one, your VM already has 4 GB queued: all you have to do is ask us via support to bump your specs up.
Measured boot. In the last thread the honest limit was "you're still trusting our boot image." Not any more. The firmware, kernel and initramfs are built reproducibly from public source, the expected launch measurement is published for every release, and an open verifier recomputes it and checks it against the CPU-signed attestation report your own machine hands you over SSH, before you type a LUKS passphrase. The guide, the source tarball and the verifier: https://servury.com/docs/guides/measured-boot/
Our own control plane. New Blackbox machines run on QEMU/KVM under a wrapper we wrote (Rust, one systemd unit per guest). No Proxmox, Virtualizor or VirtFusion in the path. Every guest is an unprivileged process with an empty capability set, seccomp, a private mount namespace where it cannot see another guest's sockets or disks, a device allowlist, private PIDs, and no ability to open a network socket of its own. SEV-SNP protects you from the host; this is what protects you from a neighbour who escapes QEMU.
Custom ISO from any URL, attached as a CD, boots first when you say so.
Console logging is off by default, and it's a per-VM switch on the Console tab. Nothing your kernel prints to the serial port is written on the host unless you turn it on.
Abuse reports are read by a person before anything happens, on every plan, not just the top one.

Everything from the first thread still holds: no guest agent and no port for one, LUKS you unlock yourself over dropbear, /dev/sev-guest exposed so you pull the attestation report from the silicon, no email, no phone, no KYC, 11 cryptocurrencies through our own processor or Stripe or cash by mail, zero access logs anywhere including the looking glass, and the site works with JavaScript off. BYOIP, self-managed rDNS - I could go on.

Plan

Blackbox Core - $9.99/month, $29.97/quarter (USD). Any term from 7 to 365 days, prorated.
2 vCPU, AMD EPYC 7543 | 4 GB RAM, SEV-SNP encrypted | 50 GB NVMe on a ZFS mirror
1 dedicated IPv4 + routed /64 | 10 Gbps unmetered | KVM, full root, UEFI
Montreal, Cologix MTL2, our hardware, AS395904, 23.155.44.0/24, 2602:f41c::/36
Templates: Debian 12/13, Ubuntu 24.04/26.04, Rocky 9, AlmaLinux 9/10, FreeBSD 14/15, OpenBSD 7.8/7.9
Order: https://servury.com/

Bigger tiers exist on the site (up to 8 vCPU / 32 GB / 400 GB). Stock note, since I'd rather say it here than have you find out at checkout: the node is nearly full, Core and the next tier up are available now, the two larger ones return after the RAM upgrade landing next week, and lots more stock when we'll rack the second node at the end of the month.
