All Blizzard Services Packet loss once every 10 minutes

Technical Support
1

I posted in an existing thread already near the bottom but not sure if it was seen so making a new post to be sure.

For the past 6 or 7 days I have had really bad lag spikes and I am pretty sure it is on Blizzard’s end but I could be wrong, here are some notes:

  1. I have been getting lag spikes for the past 5 days on Blizzard services, it appears to be only Blizzard services and no other service. I have done pings to google and blizzard game servers on my command line during the time of the lag spikes and google is not affected but blizzard services are. I get about a 20% packet loss rate on blizzard.
  2. Weirdly, it always happens every ten minutes on the minute. So for example, 9:00pm, 9:10pm, 9:20pm are times it happens. It is so strange it always happens every ten minutes and lasts about a minute then goes back to normal. This is continuous, it is not only at night or only the day, it is every 10 minute interval 24 hours straight. Is there some internal Blizzard code which runs every ten minutes that might cause this?
  3. Here is one of my WinMTR snapshots during the spike:

| WinMTR statistics |

  1. I Here is my Overwatch Network Tab During a Spike. The right monitor is Overwatch and the left is my windows network tab. ~https://imgur.com/a/Lt9QaRr~, the Overwatch “Loss Out” goes to 20% - 30% for a minute then stops, this happens each spike (again, this is for all blizzard services, like WoW and Hearthstone too, for about a minute spikes and happens every ten minutes exactly.) Does Loss Out mean outgoing on Blizzards end? My side seems to look good. If you look at the TCP connections, the packet loss section does not go up from 0 which seems weird since the “Loss Out” is between 20% and 30%.

Let me know if I can help more, I would love to get this solved it’s been really annoying! If you need more technical info / logs let me know!

Also, since this is for all Blizzard services should I cross post somewhere else? I posted in Overwatch since you had the nice network graph in game lol :slightly_smiling_face:

Hi, volunteer here. Generally, you’ll always want to start a new thread because piggybacking can make tracking replies/helping everyone difficult.

Now, let’s try to figure this out…

Not to my knowledge. Sometimes packet flooding on your router/modem, or an IP release/renew time set to 10mins can cause this type of problem. Those are things you’d need to investigate with your ISP.

Your WinMTR data seems very incomplete. There should be a lot of hops between you and the servers, which are not present in this test.

No, it’s the opposite. You can find information about the Netgraph here: Blizzard Support - Diagnosing Overwatch Network Problems

LOSS OUT: Outgoing Packet Loss

This is an estimated percentage of packet loss from your game client to the server. Small amounts of packet loss will usually be unnoticeable, but any consistent number above zero may indicate a problem getting data from your client to the server.

If you’re not having problems with other services, then chances are the problem is with one of the many ISPs between your own ISP and the Blizzard server.

Thanks Nicole! That Packet Loss out on my end is all I needed to know. Now that I know it is my problem I can take it from here :laughing:

I think you are on to something with IP release / renew. Ill check my router settings and if nothing is there contact my ISP.

And I live in a popular city so I assumed there was only 2 hops since I would be close to some hub.

You can probably close / archive this thread. Thank you so much, I really appreciate it!

Stee,

The reason you only have 2 hops is because you’re on Verizon FIOS which uses ipv6 all the way to your house. Because of this, standard tests don’t work for you since there’s no ipv6 address to test at the moment.

Keep in mind we’re also happy to keep discussing this with you - we just may be limited how much we can help on the forums because of those limitations with our normal forum testing utilities. If checking/extending your DHCP lease on your router doesn’t help out, you might be better served putting in a ticket where we can collect your MSInfo file without risks to privacy.
