    Nearly 29% of Solana Stake Went Offline. The Chain Kept Making Blocks.

    Published September 26, 2026

    TeraSwitch lost internet at 13 sites on Aug. 12, 2026. The Solana Foundation says nearly 29% of stake went offline. Blocks still landed.

    Nearly 29% of Solana Stake Went Offline. The Chain Kept Making Blocks.

    Your Solana wallet may have worked on August 12, 2026. That does not mean the network had a quiet morning. A hosting company used by many validators lost internet connectivity.

    The Solana Foundation later said nearly 29% of the network's stake went offline. Blocks still landed. A live chain is not the same as zero impact.

    What TeraSwitch confirmed

    TeraSwitch published a postmortem titled "Internet Outage Event at Multiple Sites" on its status page.

    The incident date is August 12, 2026. TeraSwitch lists the regions affected as EU and APAC. The first alarm fired at 03:49:52 UTC. Reconvergence began at 04:16:15 UTC. TeraSwitch measures full recovery at 33 minutes from the first alarm, with 13 of 31 sites affected.

    The named sites are LON1, AMS1, AMS2, AMS3, DUB1, DUB2, FRA2, SGP1, SGP2, TYO1, TYO2, and TYO3. TeraSwitch says it intentionally and temporarily removed MIA1 in North America from the backbone as a containment step. Other North American data centers were not affected.

    TeraSwitch traces the cause to a stale default route (0.0.0.0/0) originated by an MIA1 edge router. That leftover static route sat unused until routine transit-provider maintenance withdrew the local external default. The static then entered BGP. A digit transposition in a route-map caused copies sent toward EU and APAC to carry a no-export flag. Receiving edge routers treated the stale default as locally originated. Because of no-export, they could not advertise any default to their spines, so those fabrics stopped forwarding internet-bound traffic.

    TeraSwitch says the affected workloads included Solana validator and RPC nodes, which lost internet and inter-site reachability for the duration of the event.

    What the Solana Foundation says

    Jacob Creech, Solana Foundation VP of Technology, described the event in a September 14, 2026 article.

    The Foundation says a routing failure with Solana's largest infrastructure provider knocked nearly 29% of the network's stake offline. It also says blocks kept being produced and transactions continued to land. "Users likely never noticed" is the Foundation's statement, not an independent check of every wallet.

    The Foundation links the provider's full recovery to just over 30 minutes. TeraSwitch's postmortem says 33 minutes from first alarm to full recovery.

    The Foundation says TeraSwitch had hosted 38% of the network's stake the prior year, and that the Foundation worked to bring that share under 30% before this event. It also says DevNet, the developer test network, lost roughly three-quarters of its stake in the same event and recovered without a coordinated restart.

    The first changelog note was narrower

    The August 13 changelog reports an incident at 04:01 UTC on August 12, 2026. It describes a TeraSwitch routing issue that impacted its Frankfurt location, where several Solana validators are hosted.

    TeraSwitch's later postmortem lists 12 EU and APAC sites plus MIA1 containment. That is a broader picture than Frankfurt alone. The two official records do not match on scope. This article does not pick a winner.

    The changelog says the issue did not result in network downtime because not enough validator stake was affected to break the consensus threshold of about 33.33%. That threshold figure comes from the Foundation changelog.

    The changelog also embeds a Foundation social post fragment that says 597 of 699 staked validators. The page does not reproduce the rest of that post.

    What this means if you hold or stake SOL

    A live ledger is not the same as every wallet app working. TeraSwitch says Solana RPC nodes at the affected sites also lost connectivity. An app that talks to one of those RPCs can fail even while other RPCs and the chain keep running.

    Solana's staking FAQ says delegating tokens does not give a validator ownership or control over them. Rewards still depend on validator uptime and commission. A validator that missed votes can earn fewer vote credits that epoch, which can reduce that period's rewards. These records do not show a specific reward figure for any named validator.

    One provider at nearly 29% of stake, as the Foundation describes it, sits below the changelog's stated consensus threshold of about 33.33%. It is still a large share for a single host. The Foundation's own 38% to under 30% account is the evidence for that concentration. CryptoWorkPro has not taken its own census.

    What remains unknown

    CryptoWorkPro has not independently counted the 29% stake figure, the earlier 38% figure, or the 597 of 699 validator fragment.

    Solana's status page, checked on September 26, 2026, showed all systems operational. The recent past-incidents list on that page did not include August 12. A missing status-page row is not proof that nothing happened.

    These records do not show whether any specific user's transfer failed, or how much any named validator's rewards changed.

    The August 13 changelog linked a different TeraSwitch status URL for a July 29, 2026 "Global - Internet Instability" incident. That page includes a deleted August 12 investigating note saying a distinct incident was opened instead. The August 12 postmortem of record is the kwg2ffkjg5q1 page cited above.

    What to watch next

    Check the live TeraSwitch postmortem for revisions. TeraSwitch says one item remains under review.

    If you stake, you can look up the validator and stake account on Solana Explorer. Do not treat a marketing uptime claim as a measurement of this event.
