Do good providers balance at the node level?
For such a scenario:
If on the same node, everyone's vps has high traffic during London Time 6-10 pm, will AWS, Azure, Hetzner, Netcup, etc automatically transfer some vpses to other nodes to reduce the rush hour drama, like we do teleworking, flexible working schedule, car pool, to reduce or avoid the traffic during rush hours?
Just curious, because if there is no balancing, the node will freeze or congest during those rush hours, unless high level of overhead redundancy is available, which almost guarantee higher price tag.

why would they do that?
put a 10gig in hypervisor/node and call it a day. or maybe 100gig NIC.
if a particular vm is using majority of the bw, then throttle them down
Probably forced throttling is the easiest way to reduce the rush hour traffic.
Then if that vps only uses 2-4 hours everyday but only during rush hours, seems throttling will cause a lot of customer reactions.
What do you mean by that? Even if all bandwidth is utilized and netlink saturated, it won't affect the
node itself or the CPU. The big ones normally have link aggregation to the switch so they have quite a lot of redundancy for such cases. The smaller providers are the ones who usually get affected by this, but also depends if they oversell. Obviously if it's a $10/year deal, with 100 VMs
on a node and everyone is "promised" a shared 1gbit link, things will get rough.
To reduce rush hour congestion:
If every vps reaches its peak during those rush hours, cpu and ram and disk i/o may all reach peak performance. Yet, vpses are generally oversold, about 2 to 3 times more than the cpu and ram, so it may freeze the node if every vps is at the turbo mode.
how can we as end user elevate our tier? probably use money. hope there are some cheaper ways.
It is like fast lanes vs slow lanes, and there are car pool lanes, and emergency lanes, on highway. We mundane joes at LET probably mostly stay in slow lanes.
buy,buy,buy, oh,yeh.
so there is a reason why aws, azure, gc, etc are more expensive, as they have more redundancy and more overhead.
not sure where hetzner, netcup, php-friends, liteserver, hybula stand when comparing to these first tier players.
It's the difference between using your drink coupons and staying within the resort premises vs staying at the motel across the across street and finding your own trouble.
Yeh, rich vs poor. As always.
This is definitely one of those things you'd default to no on, and only accept a different answer if explicitly stated by the provider.
Get 10 VPS across a wealth of reasonably recommended providers, including the top clouds like AWS and Azure. Compare uptime over 10 years. The difference will never justify the big name clouds.
The big name clouds are at their best by providing you with all of the solutions you need to scale on demand. A strong API, object storage, block storage, database as a service, all that jazz. They're not objectively better, they're just more prepared for customers who need to be able to scale their apps on demand.
So as we LET customers with no need for sophisticated requirements, actually we are at disadvantage to use these big players. To a certain degree, I agree with you.
You're also paying for a metric shit ton of checkbox security and turn-key compliance.
If you have any customer contracts that have particulars..... The bulk of the work to prove your house is order is done.

On the flipside, I've always wondered how low-end hosts do it.
I know each provider is different, but do the majority use RAID for example in case an HDD/SSD fails?
Majority use RAID is probably a safe statement, but if it's not stated, always ask.
For storage vps, I paid special attention. Liteserver is raid 10, all others, hosthatch, inception hosting, etc, use raid 5 or raid 6. For general vps, I see clearly that php friends, netcup, hetzner have raid 10.
You can buy/reserve bandwidth allocation to avoid this, but it does not look like an issue to me if the provider takes care that no one abuse the gigabit port 24/7.
Also, recently we see a lot of nodes with 10gig uplinks, so should become less of an issue.
