Solana Webhooks - Backfill in Progress

What to do

• Check whether you use Alchemy Solana. Check your stack

  Paste a package.json, lockfile, Terraform or a list of domains at down.guide/stack to see every provider you depend on.

• Confirm your retries, queues and scheduled jobs caught up after the 21h 16m it lasted.

  Anything that failed between 2026-06-12 20:14 UTC and 2026-06-13 17:30 UTC may need a replay.

Updates from Alchemy 2

   Between June 11 and June 12, Solana webhook delivery was disrupted. An internal service issue caused repeated disconnects from the Solana data stream over a ~24 hour window. During each disconnect, events were not recovered, resulting in missed webhook deliveries. This has been resolved. Webhooks are delivering normally for all new events as of June 12 19:30 UTC. If you have active Solana webhook subscriptions, you may notice two things: - Missed events - Some events from the incident window (June 11 19:43 UTC through June 12 19:30 UTC) may not have been delivered. We are working to backfill these. - Possible duplicate events - As part of the backfill, some events from the incident window may be delivered more than once. We recommend handling deduplication on your end using the transaction signature if you haven't already. - New events from June 12 19:30 UTC onwards are unaffected - deliveries are complete and accurate. We will update the status once the backfill is completed. We're sorry for the disruption.
