Helius had 57 outages in the last 2 years totaling 128h 53m of downtime — averaging 2.3 incidents per month.
There were 57 Helius outages since August 21, 2025 totaling 128h 53m of downtime. Each is summarised below — incident details, duration, and resolution information.
We experienced a delay in archival block indexing for a range of mainnet slots at slot 439344001 (epoch 1017). Backfill is in progress and most slots have already been restored; a small number remain and are being reindexed. Live streaming and recent blocks were unaffected.
This incident has been resolved.
The global network appears to be in a degraded state. This impacts both the Solana mainnet network and Helius RPCs. You may experience elevated errors, latencies, or delayed data. Service will be restored as soon as possible.
The network is impaired in Amsterdam, Frankfurt, Tokyo, and Singapore. Other regions are healthy.
Network recovered. Systems are coming back to normal. Team will monitor and verify all functionality before closing incident.
We are continuing to monitor for any further issues.

A power outage in our SGP data center is the root cause. We've routed traffic away from the affected DC, so you may see elevated latency on Singapore-routed requests in the meantime. All other regions are unaffected.

Fix has been implemented and latencies are returning to normal.

We are currently investigating network connectivity issues in the EWR region
The network connectivity has been partially restored, we are still monitoring until failures are fully gone and the issue is fully confirmed resolved.
This incident has been resolved all EWR traffic and connectivity has recovered and routed back.

From 13:26–14:14 UTC there was an incident involving transaction landing and Laserstream streaming, during which some users may have seen failures to land transactions and/or lag in Laserstream. This was caused by a Solana network partition at an epoch boundary, where a validator forked off and began emitting broken shreds. As a result, some parts of the network observed the issue while others did not.
We are investigating decreased transaction landing rates

Devnet RPCs are currently returning service unavailable
We are continuing to investigate this issue.
We have identified the issue and are currently working on a fix
Issue found, fixes have been implemented and we are now monitoring devnet rpcs

We've identified a likely upstream issue with Cloudflare and have escalated to them. As a workaround, switch from the mainnet endpoint to beta.helius-rpc.com, which does not route through Cloudflare.
Issue was mitigated yesterday at 7PM PDT (2AM UTC+1) by working around the CloudFlare degradation. If you are still experiencing issues, we recommend switching to our new edge gateway, Gatekeeper: "https://beta.helius-rpc.com". Gatekeeper is now recommended for production.

Devnet is currently returning {"code":-32401,"message":"Bad request, please try again later."}
Issue has been resolved, Devnet RPC calls are back to normal
We are investigating increased latency on some RPC requests on DEVNET
The issue has been identified and we have applied a fix, should see gradual improvement within the next 20-30 minutes
This incident has been resolved, latencies have returned to normal
Frankfurt nodes were timing out incoming requests from beta.helius-rpc.com endpoint (Gatekeeper Beta)
Frankfurt traffic will now fallback to Amsterdam
Traffic to Frankfurt is no longer rerouted and is operational
LaserStream Preprocessed Transactions is currently down in FRA. Connecting to the FRA endpoint will fail.
A fix has been implemented. Customers connected to Preprocessed Transactions (Beta) in FRA might see slightly elevated latency. All transactions are streamed now.
We have identified the root cause. A fix has been implemented. Latency for Preprocessed Transactions (Beta) in FRA has returned to normal levels.
This is due to routing issues at a Cloudflare PoP affecting a subset of traffic. We strongly recommend switching to https://beta.helius-rpc.com, which bypasses Cloudflare. Note: the Webhooks REST API (/v0/webhooks) is not yet supported on beta.
This incident has been resolved.
The Solana DEVNET cluster has been halted due to a planned restart to rollback some feature gates. You may see stale data or increased errors as the restart progresses.
This incident has been resolved.
We have identified an issue that is impacting the shared Devnet cluster, we have deployed a fix and waiting for the issue to resolve.
