+## Edit
+As of 2024-10-18 20:07 UTC testnet is back online. The instructions below are no longer relevant. Nodes that haven't yet joined the cluster will need to update their shred version and start normally:
+
+    --expected-shred-version 27799 n+
+***
+This testnet restart is NOT urgent. Follow these instructions when you have time, but don’t skip sleep or disrupt other plans for this.
+
+## Summary
+In order to restart testnet on v1.18.26 we need to roll back 3 more feature gates that are not yet enabled on mainnet-beta.
+
+|Attribute|Value|
+|---------|-----|
+|Validator version|Agave: v1.18.26|
+|Snapshot slot|296877183|
+|Restart slot|296877184|
+|Shred version|27799|
+|Expected bank hash|ABuvd5grMYhbrjeLmu3qCNqiD8DaDRw6oyboMgZfaQS5|
+
+
+## Step 1. Stop validator process if you haven’t already
+
+## Step 2: Install Agave v1.18.26
+This is necessary in order to create the correct snapshot in step 3.
+
+Agave:  `agave-install init v1.18.26`
+
+Frankendancer: Please switch to Agave for this restart and the subsequent upgrade/downgrade cycle.
+
+## Step 3. Create snapshot
+This command creates a snapshot but removes 3 activated v1.18 feature gate accounts.
+
+    agave-ledger-tool --ledger <ledger-path> create-snapshot n+    --incremental n+    --snapshot-archive-path  <snapshot-path> n+    --hard-fork 296877183 n+    --deactivate-feature-gate n+    7uZBkJXJ1HkuP6R3MJfZs7mLwymBcDbKdqbF51ZWLier n+    tvcF6b1TRz353zKuhBjinZkKzjmihXmBAHJdjNYw1sQ n+    decoMktMcnmiq6t3u7g5BfgcQu91nKZr6RvMYf9z1Jb n+    --  296877183 <snapshot-path>
+
+
+The output should include this at (or near) the end:
+```
+    Successfully created snapshot for slot 296877184, hash ABuvd5grMYhbrjeLmu3qCNqiD8DaDRw6oyboMgZfaQS5: /home/sol/ledger-snapshots/incremental-snapshot-<BASE_SLOT>-296877184-<SNAPSHOT_HASH>.tar.zst
+    Shred version: 27799
+```
+
+Note that each operator's snapshot file name may contain different base slot number and hash, but 
+* the bank hash should be ABuvd5grMYhbrjeLmu3qCNqiD8DaDRw6oyboMgZfaQS5
+* the second slot number should be 296877184
+* the shred version should be 27799
+
+Once you have created a snapshot move all the other snapshots to a backup directory, so your snapshot directory contains one full snapshot and one incremental snapshot. Note that the <BASE_SLOT> in these two filenames should match.
+
+    snapshot-<BASE_SLOT>-<BASE_SNAPSHOT_HASH>.tar.zst
+    incremental-snapshot-<BASE_SLOT>-296877184-<SNAPSHOT_HASH>.tar.zst
+
+If you fail to create a snapshot see the appendix for possible fixes.
+
+## Step 4: Update startup config and start your validator
+### Agave
+Add these arguments to your validator startup script:
+
+    --wait-for-supermajority 296877184 n+    --expected-shred-version 27799 n+    --expected-bank-hash ABuvd5grMYhbrjeLmu3qCNqiD8DaDRw6oyboMgZfaQS5 n+
+
+As it starts, the validator will load the snapshot for slot `296877184` and wait for 80% of the stake to come online before producing/validating new blocks. 
+
+To confirm your restarted validator is correctly waiting for 80% stake, look for this periodic log message to confirm it is waiting:
+
+    INFO  solana_core::validator] Waiting for 80% of activated stake at slot 296877184 to be in gossip...
+
+And if you have RPC enabled, ask it for the current slot:
+
+    solana --url http://127.0.0.1:8899 slot
+
+Any number other than `296877184` means you did not complete the steps correctly.
+
+Once started you should see log entries for “active stake” visible in gossip and “waiting for 80% of stake” to be visible. You can track these to see how the stake progresses.
+
+
+***
+
+## Appendix (use this only if step 3 failed)
+
+If you get an error like this:
+
+    Error: Slot 296877183 is not available
+
+Or this:
+
+    Unable to process blockstore from starting slot <slot> to 296877183; the ending slot is less than the starting slot. The starting slot will be the latest snapshot slot, or genesis if the --no-snapshot flag is specified or if no snapshots are found.
+
+Your snapshots directory contains a snapshot that is for a slot `>296877183`. If you also have a snapshot for slot `<=296877183` then move snapshots for slots `>296877183` to a backup directory and run the `agave-ledger-tool` command again. If you do not have a snapshot for slot `<=296877183` then you will need to download a snapshot
+
+If you successfully created a snapshot, resume the instructions above starting at Step 4. If you are unable to create a snapshot, follow the instructions below on downloading a snapshot.
+
+If you couldn’t produce your snapshot locally follow these appendix steps
+
+### Step 1: Download a snapshot from a known validator
+
+If you are unable to generate a snapshot locally for slot `296877184` you will need to download one from a known validator. Add these lines to your startup script.
+
+    --known-validator 5D1fNXzvv5NjV1ysLjirC4WY92RNsVH18vjmcszZd8on n+    --expected-shred-version 27799 n+
+Remove the flag `--no-snapshot-fetch` in your startup script if it is present.
+
+### Step 2: After download, restart
+
+Verify that you have a new snapshot in your snapshot directory.  If the snapshot is done downloading, stop your validator process.
+
+Add the flag `--no-snapshot-fetch` to your startup script
+
+Resume the instructions above starting at Step 4.
