"Recently, the Arbitrum Sequencer experienced a stall at 10:29 AM ET due to a significant surge in network traffic. Consequently, I began investigating the hourly number of Arbitrum blocks and proceeded to compare Arbitrum's performance with that of Optimism and Ethereum networks. Subsequently, I delved into analyzing the impact of this issue on Ethereum's fees.

Upon investigating the number of Arbitrum blocks, it became evident that there was a sharp decline in the hourly count. However, it fortunately seems to have returned to its normal trend.

Furthermore, upon comparison with Ethereum and Optimism, it is apparent that neither Optimism nor Ethereum encountered any issues with their blocks. Interestingly, this issue did not affect the average gas fee on the Ethereum network."
