This is why it's only affecting some players some times on certain shards. Sharding is an intricate system. It's a big bear you do not poke lightly.
First of all THANK YOU. This is what I suspected.
Now: Ive been making some notes.
First, during peak times we have what you could call "choke points". Using a Venn diagram, draw two circles around Boralus and Zuldezar, have them intersect and you will see the issue as far as the capitals are concerned.
I have literally seen the lag drop off as soon as I move out of those areas, and this MAY be due to war mode vs non in a congested area. Peak times are about 5pm through to about 9pm approx.
Second, have the techs look at places like Tol Dagor and the zone around Corlain, as I have noted what id call "spikes" of server lag in those areas, BUT as soon as you move away the effect lessens..which looks to me as if Im moving from one shard to another.
These are farm areas, and the player capacity rises and falls as people move off..draw a circle between I think Falhaven and Corlain, as the lag issues appear intermittently.
I have noted a degree of "fall off" as I shifted location, the lag lessened and then rose again almost as if on a gradient curve. The greater the area population, the greater the lag..so I would venture a guess it may be shards AND congestion both.
Thirdly, looking at mail and GBank lag, they are concentrated in capital areas BUT when using mobile banking, I experimented with putting down banks in different areas...the results were again almost in a slow upward curve.
Question: by shards do you mean normal sharding or do you mean war mode vs not?
Next: I dont know if this is relevant, but Id like your feedback on this.
Lets say that I go into a group to kill a boss. I am sharded into that group and my latency spikes (as it would) as the shard is with US servers.
BUT.
What I have then noticed is that when I hearth back to Zul or to Boralus, my latency does not drop off..I have to hearth to Dal to get it to reset. Whether this is an issue peculiar to me or if its more widespread I dont know..but Ive tested and again the results are the same every time.
I dont know why and I imagine your techs may be able to answer this, but leaving a group should initiate a change back to OCE servers..this isnt happening in those capitals.
That could be something to look at as maybe a symptom of the problem, or it may be linked to the sharding for those areas. I have noted my latency stays at 11/150 if I stay in Boralus, when I move to Dal that drops within a few minutes.
Could part of this be due to an incorrect or slow "soft reset" on the actual server connections?
One last point thats happened only in the last few days.
From time to time we get letters from NPC's..flavour stuff. I try and save those and I cant, I try to delete it and I cant.
On each and every occasion it has taken a shift to Dal and then back to Zul or Boralus and it can then be deleted.I cant say if this is part of the issue at hand, but its a new factor I have seen in the last few days, so Im reporting it anyway. If it fits, great, if not, well youve been advised :-D
Not a tech so dont know if this is useful or not, but there it is.
You are not by any means obligated to do this, but this is currently one of the most constructive things you can do in our eyes.
If you need any testing done, if you need reports, if you need data, all you EVER need do is ask. I will be delighted to help wherever I can.- Aehl.
P.S Thank you again, Drakuloth, cant tell you how much its appreciated.
