On 22 October 2026 the Ethereum Foundation’s Protocol Cluster postponed Glamsterdam on Hoodi. The slot that came off the calendar was 26 October 2026 at 17:42:48 UTC, epoch 132,352. The same notice removed a plan to raise Hoodi’s gas limit to 200 million at that epoch. The updated configuration has no replacement epoch and no replacement timestamp. The post says it supersedes the schedule in the Hoodi announcement of 16 October.
Glamsterdam is two named pieces shipped as one network upgrade: Amsterdam on the execution layer, Gloas on the consensus layer. The 16 October announcement described enshrined proposer-builder separation, block-level access lists, and gas prices meant to follow the cost of execution and of growing the state. Those are still a design for a later activation. They did not become mainnet rules because a testnet date moved.
What happened
All Core Developers Execution call 248 is the meeting the Foundation cites. The delay is so client teams can keep looking at how EIP-8037, a gas-accounting change, interacts with contracts already deployed on mainnet. This page will not describe how a contract could be pushed through a path it used to reject. The fact in the post is enough: the rehearsal stopped while that question is open.
What the delay removes is the scheduled activation, not Hoodi’s history. Amsterdam does not turn on. Gloas does not turn on. The gas-limit step does not turn on. The Foundation says the change rolls the configuration back so a later upgrade can be scheduled cleanly. It does not rewind blocks Hoodi already produced. A postponed testnet is a calendar edit. It is not a halt of Ethereum, and it is not a chain that voted to undo its own recent blocks.
Sepolia activated Glamsterdam on 6 October 2026. That network is still a testnet, and it is not Hoodi. A feature you can see on Sepolia is not a feature on Hoodi this week, and it is not a feature on mainnet. The wrong network is still the wrong city.
Hoodi node operators are the people with a task. If a client, or a hand-edited network config, still aims at epoch 132,352, it needs a release whose notes say the 26 October activation was removed. The version table in the 16 October announcement is the old schedule. The Foundation says not to treat that table as proof a build includes the postponement. Follow the 22 October post and the notes from the client you actually run. This article will not copy a version list that client teams are still filling in.
If you hold ether, or you use Ethereum mainnet, the same post says you have nothing to do. No wallet update is required by this notice. No migration of ETH is required. A message that says otherwise is not the Foundation.
Why it matters
A testnet is where operators rehearse a fork before anyone dates mainnet. Cancelling the rehearsal means the dress rehearsal did not happen. It does not mean mainnet forked in silence. The Foundation has not set a mainnet activation, so a date that assumed Hoodi would fire on 26 October is not a date anymore. Ethereum graded 62 EIPs for Hegotá is the workplan for the fork after this one. That ranking was not an activation. Pectra changed Ethereum accounts and validators is an upgrade that already shipped, in May 2025. This page is a delay of a different upgrade, on a testnet.
The 200 million gas figure was a Hoodi setting paired with the fork. Taking it off the schedule does not change what you pay to use mainnet. On-chain fees are an auction, not a punishment, and the auction that matters is the chain your transaction is actually on.
Phishing will use the old date. “Upgrade before 26 October”, “claim your Glamsterdam ETH”, and a file that says it is a client are the usual costumes. A wallet signature is not a handshake. See Ethereum without the jargon if execution layer and epoch are still labels without a picture. See a practical checklist for keeping crypto safer before you install anything a stranger sent.
What happens next
A new Hoodi time, when client teams have one, published the same way as this postponement. A mainnet time only after that, and only when the Foundation names an epoch. Watch the Protocol Cluster posts on blog.ethereum.org. A roadmap page that still prints a Hoodi fork for this week has not absorbed the 22 October notice. We will not turn a missing epoch into a price target, and we will not tell mainnet holders to install a build for a testnet that is no longer upgrading on 26 October.
Not a recommendation to stake, unstake, buy, or sell ether. Not an activation notice. Not a client-download link.
