The Solana network, which experienced a long downtime in September, hasn't been fully down for several months, although it hasn't experienced a full downtime since then. On September 14, 2021, the Solana network was offline for 17 hours, and on September 20, 2021, the Solana Foundation confirmed that this network outage was caused by a denial of service (DoS) attack.

The Solana mainnet recently experienced performance issues again. However, it is worth remembering that software development is still in beta.

Solana team explained the following about the problems experienced in the past days:

   “The developers have made a lot of progress on this, but the work is not done. The last 24 hours have shown that these systems need to be improved to meet the demands of users and support the more complex operations that are now common on the network.

The current problem validators are experiencing is due to excessive duplication. Engineers have just released 1.8.14, which will attempt to mitigate the worst effects of this issue.

These upcoming releases aim to improve the state of the network, with further improvements expected in the next 8-12 weeks. Many of these features are currently live on Testnet and are rigorously tested here.

Version 1.8.14 is now…”

As a result of all these developments; FTX CEO Sam Bankman-Fried, nicknamed SBF, shared his thoughts on Solana's recent performance issues.

While it is true that there is some performance degradation, the Solana blockchain @still processes more transactions than any other major blockchain, SBF said.

He then went on to say although “there's more work to do”, it is “only by being ambitious” that we can “make progress” and “sometimes that means failing to hit our goals, but we still often end up further than if we'd never tried.”
