During the testnet upgrade the team identified an issue with the updated Hedera node software code. We are returning to the previous version while we investigate further.

Scheduled maintenance is currently in progress. We will provide updates as necessary.

We will be undergoing scheduled maintenance during this time.

Hedera will be upgrading the testnet to v0.5.8 (release notes: http://hedera.io/release-notes) on Tuesday, May 19th, at 17:00 UTC. This upgrade will take approx. 120 minutes to complete, during which time all network services will be offline. This patch addresses the resilience of peer-to-peer networking used in the consensus algorithm.
