Sorry if this is an already asked question, couldn't find it if so.

I'm wondering... is there a way to know if a sim is class 5 using the SL viewer tools? I mean... not just having the oland owner telling you it is class 5.

If there is, could somebody please tell me where to find that?

Thanks a lot!!

According to what I have been told, there is no certain way to tell. There was an internal number that could (and still can) be extracted, and class 4 sims were all to find below a certain value of that number. However, it has been stated that Linden Labs have commenced re-assigning numbers from old de-committed class 4 sims for newly purchased sims, so hence there should not really be any way to tell.

Go to Help/About Second Life and look for the servername (ie sim4135.agni.lindenlab.com) Any number above 2120 will be a class 5 sim. First I've heard about LL reusing old numbers but I suppose anything is possible.

Yep, the host number hasn't had much to do with the server class in a long time.

The number of remaining class 4s keeps shrinking. LL phased them out for mainland, then they said the same would happen for older void/openspace/homestead sims, so all that should be left are estate sims on the grandfathered tier (and those can be either 4 or 5).

That hasn't worked in years. There is no way to know, except to ask LL.

"If you look at Help:About Second Life, you will find a line that tells you the host on which your region is running. That will say something like sim1234.agni.lindenlab.com. If the number after “sim” is less than 2133, the region you are in is a class 4 region..."

He said that might change in the future.

Yeah, for values of "the future" including "tomorrow" when he wrote that. Second Life was migrated to a whole new network since then, and there was lots of renumbering, so don't rely on anything from 2008.

Maybe they changed their mind. Then changed it again.

Tool to Check Server Class
10-29-2009 12:54
I asked about this over on the "SL Answers" / "SL Blog" thing and was directed to this tool for sale at XStreet:

https://www.xstreetsl.com/modules.php?name=Marketplace&file=item&ItemID=1091445

It tells you if the current sim is class 4 or class 5 (and more). There's a rez-on-land and a HUD version.

I tested it on some sims where I know the server class (e.g. Spaceport Alpha is Class 4, Aglia is Class 5) and it gave the correct class. Yay!

Note: I'm not associated with the vendor of the tool. There are probably other tools that do the same thing, but I'm just happy that *any* exist!

/me would beware of trusting the class it tells you if the sim is busy or people are coming/going. I can guess how everything else it reports works and that's all kosher but I think the only way it can tell server class is by looking at the host number (which LL declared isn't valid) or by doing a bunch of math and measuring how long it takes...

FUD? Meh

If you're going to come on here and say that "Linden Lab said such and such" then please give the URL of where they said so, otherwise it's just rumor mongering.

I told you I tested the tool on sims where I know the server class and it always gave the right answer for those ones. If someone can come on here and give me a specific example of a sim of where the tool gives a wrong server class number, then great.

Sure. Look a few posts up for where I already did exactly that.

Yes, but, see, the thing is is that the set of stuff you can do in scripts is pretty well defined and there's nothing in there that will tell you which class hardware the sim host is on. It's just not there.

So.. Like I said, it's either using the host number, which LL has said is not reliable, or it's doing some computationally-expensive operation and guessing at the class based on how long that operation takes.

URLs please
10-29-2009 13:32
I've looked high and low and can't find any reference in which LL says concretely that they've changed the server numbering system. They could have, and maybe they did, but like I say, I have yet to see the evidence. If you have an URL, then please post it, otherwise I'll just assume you're blowing hot air.

My suspicion is that LL just left the system of numbering alone. After all, if it's not broken, why fix it? Changes to code can have unanticipated side effects, so why risk problems?

Uh huh. Try looking at post #10 of this thread, which has the link to Max Case asking about this.

From: Max Case
Hi.
I am wondering if it's possible to get the info on host number to server class. Info used to be on the wiki, but it's now gone.
The info in this post is a bit stale.
...
I tried through support, no answer.
I know I'm not the only one insterested in this info.


From: Torley Linden
[UPDATE] I checked with the expertise of our Concierge and Ops Teams. Things have changed, literally: the "old system" isn't applicable anymore, because ranges of numbers don't necessarily correlate with server class. Furthermore, we don't keep track of it in a way that's automatically updated, so for future purposes, it's best not to go by simXXXX number to determine server class.

Wow - talk about taking things personal and getting your panties in a bunch.

Dude, it's just a forum, nobody dies here.

This is the Second life forum, right? The one owned by Linden Lab? M Linden the CEO?

Actually, the change was made before M took over so we can not blame that one on him.

That project happened over several months, but a couple entries with details are:

https://blogs.secondlife.com/community/technology/blog/2009/05/01/updates-from-the-grid
From: someone

LLnet: We continue to work to further take advantage of our private network. Our current work is focused on renaming our server IP scheme, in order to allow us to direct public IP traffic over our private network (currently only our private Linden traffic uses LLnet). The benefit of this change will improve redundancy within our infrastructure by providing a means to route traffic to a data center that might be locally isolated by a Level 3 problem. This has occurred late last year in the Phoenix area (December 2008), and isolated all access to simulators and databases in Phoenix. Once the renumbering project is complete, we will be able to route around any local market outage, by moving traffic over LLnet from an unaffected data center (like SF or Dallas).

They're just addresses, and hosts have been moved to different physical locations *and* an entirely new set of networks since then.

For what it's worth, I did a survey today of server numbers for all sims in the old continent (Sansara).

Mainland is supposed to be all class 5, and the lowest numbers I found were 2142 (Great Urswick) and 2143 (Nick Rhodes). So this doesn't contradict the "2133" theory, I couldn't find a counterexample.

Note: these numbers are apparently subject to change when a region is restarted, so they may be different by the time you read this.
