It’s on the provider’s end. Norlys.
What Blizzard can do, and sometimes does, is to make the provider aware of it (because it also affects Blizzard’s customers).
But it obviously goes further if people contact the provider themselves and explain the issue.
And what would we need to provide the support?
Well you just explain that you’re playing World of Warcraft and you experience severe lag spikes, and the time of day it happens and for how long.
If you want to be fancy about it, you can do a traceroute and provide that. Someone did that in the other thread:
WinMTR is a program you can download that creates the traceroute.
But I would say that it’s sufficient to simply say that your internet is not operating as it should when you’re using certain applications at certain hours of the day and it’s been ongoing for a period of time.
You don’t need to be a tech wiz to complain about a product. We don’t need to be that with Blizzard’s product, so why should we with other ones?
I mean… yeah, obviously since it’s a common trend for everyone in here to be dealing with these issues all seem to use the same provider.
my estimated guess would be it’s more so the connection between Blizzard’s servers somehow? but i really don’t know.
how would you go about explaining this to their phone support though, they’ll likely just look up our connection and tell us “it all looks normal from here” ?
“oh but I’m having very bad lagg spikes, at random times and only when playing this one specific game and only while doing certain activies in the game”
idk… I’m just not very hopeful for any form of fix or support? from them when this is all we’d be able to explain, since it seems to happen at random.
It’s more the road that your data has to travel to get to Blizzard’s servers. Norlys handles that.
What you ideally want is for your data to be moving on the highway, so it gets there quickly.
But Norlys are instead directing your data through a myriad of small bumpy roads on the countryside before taking a u-turn and finally getting it to Blizzard’s servers, much later than you would have hoped.
Or in more technical terms: Your data doesn’t go to Blizzard’s servers directly. It goes through other servers on its way to get there. The fewer it has to go through, the more ideal it is.
That sounds very reasonable to me.
I mean, you’re the customer here. You’re paying, what, 300ish kroner per month for internet that you want to use to play the game you pay 100 kroner for every month, on top of the expansion that cost you 350 kroner? If your internet is not working for the purpose you want to use it, you just tell them that. Then it’s their problem to deal with and one they need to find a solution for.
If they’re rejecting the issue, you can always just rattle the saber and threaten to change your provider. Because that is one potential solution. People with TDC or Waoo or Telenor are not having this issue, so you can always just tell Norlys that if they don’t have a solution in a reasonable time frame, then you’ll consider another internet provider.
Dane here with norlys, OMEGA lag and DC every night- might aswell cancel subscription…
The lag hits Classic too (obviously, since it is a provider problem), so the last part only counts if you were so clumsy you upgraded to TWW 
After writing a very long message to customer support explaining the issue, with a log of WHEN and for HOW LONG the issue happens (20+ entries), support replied with “We dont see any issues in your area, have you tried restarting your router?” Exactly what i expected.
kind of what i expected to happen as well sadly… if this continues for much longer ill probably just end up swapping provider.
I didnt have any lagg spikes issues last night on maintenance day , but I had one big lagg spike again about 30 minutes ago , so the issues is still a on-going thing…
So, i got some information regarding this subject (it stopped for me before the expansion release)
But, apparently, norlys goes through different providers that connects to blizzard servers, atleast that’s what the guy said to me, it’s not a direct connection from Norlys to Blizzard servers, there’s apparently an inbetween and it seems to be that set connection has some issues, not quite sure how it works really, they say it’s not in their end, blizzard says the same, so it must be the middle man… idk, might be a lie, but who knows, i don’t work in this type of area.
Same issue here, Norlys provider. Everyone I know have this issue in WoW, Overwatch and Diablo.
Just want to voice in aswell. It is becoming worse and worse playing TWW. Norlys here aswell, giga lag spikes 4 times this evening already… 
Edit: And it is ONLY in blizzard games. Happening to all my danish friends playing with Norlys. People are so frustrated lol
Norlys here, same issue
So, it seems to continue, me and my irl mate has the same internet provider and the issue still exist (had it yesterday / not even 5 mins ago) Idk, at this point, i’ll probably switch provider to hypernet or whatever.
Same here. Norlys as provider. Happened just 30 minutes ago or so.
Friend i play with who don’t use Norlys never has an issue.
Dane here, same issue
Norlys provider
Pls fix
Absolute garbage provider. 2nd time talking to customer support and they say “the people in that forum post you linked are very quick at jumping to conclusion that its a Norlys issue”.
Maybe it is not their issue, but at least they should do something to nail down the problem. They are the experts - we are just paying customers
Norlys here too.
I mean, if almost all of those people are saying their ISP is Norlys… then how exactly are they “quick to jump to conclusion”? and it has been an issue for awhile now with Norlys. I called their customer support and they said they were investigating the issue but I’ve heard nothing from them so far. They haven’t announced anything on their status website either, as if nothing is wrong…
norlys is getting ddos attacks from a hacker group in Switzerland, who have many zombie computers at their disposal ( virus infected) that they can use to overwhelm the servers. Wednesday and fridays are the worst yes?
