No, they’re bugs, but Solana (average 4500 transactions per second) competes more with Visa (average 7500 transactions per second) and older blockchains aren’t even in the arena. The bugs get fixed, Solana’s pretty stable, you can see the exact numbers at https://status.solana.com/
Solana's definition of transaction is weird though. There's no way a P2P network is doing 4500 txs in the common blockchain terminology. The entire system is a house of cards waiting to crumble - just napkin the average tx size * 4500 txs * peers etc...
How are there enough transactions on Solana to get to 4500 per second? How is there possibly enough demand on a crypto network to be remotely in the same league as visa? I don't buy it.
A lot of Solanas throughput is consensus messages between validators.
But finance in general is many orders of magnitude more TPS than visa. Think about high frequency trading of derivatives of all sorts of things, and all the tiny arbitrages that can be done over all the exchanges when fees are cents. Those can easily multiply to thousands of TPS.
That’s literally what Sol was designed to do. Plus taking 20% of all NFT traffic in a year is a huge part of it. Even with consensus messages removed Sol still does more transactions than all the L2s combined.
I assure you that their status page is no indication of reliability. Ask the more serious node operators and they can tell you how frequently you actually encounter issues with the network.
