A technological upgrade on Polygon’s block production layer caused the Polygon blockchain network to go down for almost eight hours between Thursday evening and early Friday morning.
The sixteenth-largest cryptocurrency by market capitalization and one of the top gainers in 2021 had its network down for about eight hours due to a technical update that went awry last night.
To allow developers to fix the issues in a secure manner, the team decided to halt transactions, informing users of the impending unavailability.

Network update
Due to issues with the Tendermint implementation used by the Polygon PoS chain, users can expect downtime starting at 5:50 PM UTC.
We appreciate your patience. More details are in the forum and we’ll share updates when possible.https://t.co/O1MFUrKuAr

According to Polygon co-founder Bjelic, the upgrade was not expected to affect the consensus layer “in any way.” However, the network went down from 5:50 p.m. UTC on Thursday to around 1:50 a.m. UTC on Friday.
According to Bjelic, the flaw only affected the Heimdall node, and as a result, all user funds and data on the network are safe. A permanent remedy, which will necessitate more action from validators and will essentially be a network upgrade, should be available today or tomorrow.
In the early morning hours of March 11, 2022, Polygon’s operations were back to normal (UTC). Polygonscan is updated and displays transactions at the time of writing, while Polygon Bridge assures cross-network interoperability.
Polygon (MATIC) is an Ethereum layer-2 scaling solution that focuses on addressing common blockchain pain points while also providing low fees and rapid throughput to consumers without jeopardizing the security of the base layer.
Polygon is one of the most important blockchain ecosystems, with over 7,000 decentralized applications completed or under development. The network recently addressed a “high severity” vulnerability in the network’s Proof-of-Stake mechanism, putting billions of dollars at risk.
