zkSync was down for 5 hours on Christmas Day but is now back online
The zkSync network developers got an unwanted Christmas present on December 25th. The network went offline, prompting the team to “check” to find out what went wrong over the holidays, according to the team's Christmas Day announcement. According to the team, zkSync was back up after about five hours.
The zkSync Era network is now fully operational. At 05:50 UTC, one of the network's automatic security protocols was triggered by an error in the server. This issue requires teams to investigate and is now fully resolved.
We will share a full post-mortem report soon. Thank you for your…

Outages and crashes affecting blockchain networks have occurred frequently in 2023. In January, Solana experienced a four-hour outage due to a distributed denial-of-service (DDoS) attack. In March, Polygon crashed for more than 11 hours because of a bug in a hard fork. On December 15th, a sudden write explosion caused Ethereum Layer-2 Abitrim to go down for 78 minutes.
