The post Starknet stutters, turns off and on again twice in one day appeared on BitcoinEthereumNews.com. Ethereum layer-two network Starknet has experienced two outages in short succession, following its latest “Grinta” upgrade. The transition hasn’t gone smoothly, to put it mildly.  Starknet went offline for just over two hours this morning, between 2:23am and 4:36am UTC, before the team announced that the network was “back online and fully operational.” Not two hours later, however, another announcement came that Starknet was “experiencing another downtime.” The team’s latest update states it’s “deploying a fix now” and “expects the network to be operational shortly.” Status update: Starknet is experiencing another downtime.

At the time of writing, the site’s mainnet uptime tracker has logged a total of five hours and 38 minutes of outage so far today. The previous time the network experienced downtime was July 18, for 13 minutes. Starknet, which DeFiLlama ranks as the 42nd largest chain by total value locked (TVL), is classed as a “Stage 1” rollup by ecosystem watchdog L2BEAT, though this was achieved months prior to the upgrade. Rollup breakdown Starknet is far from the only network to experience downtime recently.
