OK you still don't get it.

The orange bar is the AVERAGE of your total bandwidth usage minus the top 5% of peaks. Its not your "limit". All it does is show the average. When that average hits 8,10,12Mbps, depending on your limit, then you will be "limited" to that speed on transit. Its entirely possible for peering to still hit 100Mbps and that orange bar to go over the 8,10,12Mbps threshold.

If all you're doing is running a few game servers, you're never going to hit that limit so don't worry about it.

eh not so easy to set up limitation on iproviders specially if you have no clue what every single provider is doing but anyway for gameserver the bw needed in not too bad

Rule of thumb is:

Europe = Peering
Rest of the world = Transit

But it all depends on the individual ISP's connections too. For example Virgin Media in the UK prefer to use DTAG (German transit link) rather than LINX (peering).

To be clear you can no longer burst on transit in most cases only, peering remains at 100Mbps, depending on the bandwidth package you choose. Its all described in the regime...

The average bandwidth in use is logged every 5 ish minutes.

The logs for the last 30 days are taken and the highest 5% of the values are discarded leaving the remaining 95%.

The highest of the remaining values is taken as your 95 percentile.

The bandwidth graph showing 200k is saying that for the last 30 days your 95 percentile was 200k. This is way below the 8/10/12 limit.

If you were to have a 95th percentile above 8|10|12mbps (depending on your server) you server will then be limited to the 8|10|12mbps until the data is recalculated. During this time you could no longer burst to 100mbps.

I believe the system re-calculates this every day for the previous 30 days.

Now the problem is if the limit is 95percentile why is my 95th percentile bar on the daily graph marked at 200k? Hope this makes it clear cause after reading the 10 pages of the bandwith post over and over i still can't make out what is sayd in there and i guess with me most of the other people who still asked questions which were never answered. Now i'm not taking this on anyone in here but can anyone of you who seems to have understood this matter perfectly explain how it works in a dumb proof way?
You obviously don't read, because its there in plain writing and has been since the beginning.

Bandwidth allowance is based on 95th percentile

If the bandwidth average exceeds 8Mbps (minus the top 5% of "peaks" in bandwidth):
…OVH > Internet (Peering) speed will remain at 100Mbps.
…OVH > Internet (Transit) speed will be dropped to 8Mbps.
Bandwidth priority: Low

95th percentile is calculated daily and adjusted accordingly
It tells you its based on the 95th percentile, your 95th percentile limit on this example is 8Mbps (in red). While it may not be 8Mbps for your server (it could be 8, 10 or 12) it states the drop limit on the Kimsufi server page.



Understand now?

The actual limit is either 8, 10, 12 or 15Mbps, depending on the server you have. If its not a Kimsufi or RPS then there is no limit unless you're on Burstable or Traffic series, and traffic series doesn't have a 95th percentile. Its all explained in the bandwidth regime post...

ok but what is the actual limit that will get my bandwidth limited than?

Why is it strange? The 95th line in the graph will show what you're currently using.

makno
15-02-2009, 15:08
well it doesn't have much sense than, if i'm allowed 100Mbit and the 95th percentile shows at 0.2mbit kind of strange.
I realized i miscalculated but it was 6 am and had to get some sleep

http://en.wikipedia.org/wiki/Burstab...5th_Percentile

Basically, cut the 5% highest peaks and that is where your 95th avg is.

For the record: 200kbit is 0.2mbit -- not 25mbit.
Even if you meant 200KByte/s, that only adds up to less than 2mbit.

sorry to be a pain guys but i've been reading the andwidth guide and still not making much sense out of it. mostly because i checked my graphs today and i see an orange line at about 120kbit were the peak is at 200kbit. Now 200kbit is somewere around 25Mbit which is far away from the 100Mbit limit. Also in the guide i keep seeing 95percentile but of what? Is it 95% of 100Mbit? Maybe it's me not understanding english anymore but i think a guide shouldn't be that cryptic. Hope someone can answer these questions.

I'll have a look into ufw but maybe i'll try first on my home box just to avoid having to reinstall the os. I doubt that the 100Mbit will be filled, spike was at 1Mbit with nearly full server so should be good. That if i understood the bandwith usage policy as to me is still not clear at all.

Most firewalls should allow you to filter ports by IP addresses.

I know this is fairly simple in ufw. Iptables should allow this functionality also.

For a gaming server I think kimsufi is fine as long as your bandwidth doesn't get limited to non-burstable. In any case 99% of any lag would come from players unless your server is heavily overloaded. However if you do find their is too much lag ovh servers would (theoretically) offer lower latency but not much difference really.

Hi everyone, i'm posting to praise ovh/kimsufi.
Ordered the server on monday evening and was dispatched yesterday (25h later) even if there was no 24h availability.
I had previous experience with linux so decided to go for ubuntu as i need the dedicated machine to run a couple of game servers. My question is if anyone here would suggest ovh or kimsufi for better latency. I'm currently using a kimsufi xl burstable for testing but considering upgrading to a better box next month. Another problem is that i never configured a firewall and was wondering if it's possible to allow ssh connection only from a set of ips. Anyone?
