Solana – which prides itself on being a censorship-resistant decentralized network – relies heavily on cloud computing, like all other blockchains. As a result, you remain vulnerable to central service providers, who can stop the service on the network at any time.
Yesterday, one of Solana’s major networking providers decided to stop offering its services to devices running on Solana nodes and take them all offline.
20% of the network state and 40% of the nodes are offline
Hetzner Online GmbH – the seller who removed all Solana nodes offline – closed more than 1,000 Solana nodes overnight. Although many of them back up, operate and use the services of competing cloud-based service providers, there is no guarantee that a similar event will not happen in the future.
Well, we should talk about banning Hetzner Tweet embed Contract.
I monitored the decentralization of Solana’s infrastructure throughout the month of August via a tool I created.
40% of Solana validators live on the hetzner, which adds up to 20% of the total network effort.

Hetzner’s decision didn’t affect Solana hard enough to stop Grid completely – but she was halfway there. In order for Solana’s consensus mechanism to stop working — virtually stopping all activity on the blockchain — a total of 39% of the network’s share must disappear.
Hetzner’s decision cut 20% of the network — and if Solana’s two other major vendors, AWS and Equinix, joined in, 65% of his share would have gone up due to smoke.
Hetzner’s opinion of Blockchain was already known
Although Hetzner gave no warning to contract runners before taking them offline, the company’s sentiment toward blockchain networks was already made public earlier this year. In a Reddit post on the network provider’s official subreddit, a company spokesperson confirmed that nodes are not allowed to run on Hetzner’s bandwidth.
“Our products are not allowed to be used by any mining-related application, even if it is remotely linked to it. This includes Ethereum. Includes Proof of Stake, Proof of Work, and related applications. Includes commerce. This is true for all of our products, except co-location. Even if you run a single node Only, we consider it a violation of the Terms of Service.”
Unfortunately, this Reddit post may not be enough to get the message across to Solana’s contract contestants. If the contract administrators were warned in advance, this situation could have been prevented by switching to other cloud service providers.
Although the Solana node outage did not cause any permanent damage to the network, the incident should be taken as a warning to the community that although the blockchain is decentralized, it is still vulnerable to third-party interests.
