On Wednesday morning, the Ethereum blockchain appears to be having connectivity issues with the respective service providers.

• In a service announcement shortly after 08:00 UTC, Ethereum infrastructure provider Infura stated that it had an outage for the Ethereum mainnet API and is investigating the issue.
• Infura provides API access to the Ethereum network for other applications and services.
• Due to the outage, some Infura users have suspended Ethereum services, including Metamask and Binance.
• While the situation is currently evolving rapidly and is far from clear, bugs in Infura can arise from problems with Ethereum itself.
• Binance and Blockchair tweeted shortly before the press release that the Ethereum blockchain may have been split.
• Blockchair added that the issue was fixed by updating Geth, an Ethereum client.
• "At some point, Ethereum developers made code changes that today caused the chain to split, starting at block 11234873 (07:08 UTC)," Nikita Zhavoronkov, Blockchair's lead developer, said on Twitter.
• Calling it "a technically undeclared hard fork," Zhavoronkov added that third-party services would need to be updated to resolve the issue.
• Speaking with CoinDesk, he said the changes may have been made months ago, leading to the split today.
• “Those who haven't updated their get-nodes for a while (I suppose, several months at least) split with those who had new get-nodes,” Zhavoronkov said, adding that the Infura outage is likely arose due to the same problem.
• According to CoinDesk, the price of the Ethereum cryptocurrency has not changed at the time of publication.
• This is sensational news and CoinDesk will provide updates as more information becomes available.
