Happens intermittently no particular one time period. Started after last weeks update.

[Nazzo]

ISP: Verizon Fios
Location: North Virginia USA
Occurrence: On and off but often, The issues only started up after last week's server updates. I had no lag whatsoever in beta 4, early access, or week 1 of release.

This seems to be a running theme. Seeing so many people located in VA with Verizon as their service provider posting in this thread and others complaining of the exact same issues. Myself included.

- Verizon FIOS
- USA, Northern Virginia
- From early afternoon until at least 5 AM EDT
- Ticket number: VADQ0CZQSJ

Issue manifests lag for 1-5 seconds every 5-15 seconds. During the lag, all players and monsters stand still but I am able to move around and continue trying to cast spells or interact with objects. This is especially noticeable in dungeons.

EDIT: This issue only started occurring since last update.

Is there anywhere you have a list of ISPs this issue has been resolved with?

I've been playing the game through a VPN for about a week now to circumvent the slideshow.

[Theldane]

ISP: Comcast
Name: Ghaledunai Akeral
Country: USA (CA)
Occurance: Pretty much every 30 mins to an hour or less when playing at any point during the day, suddenly the game will slow down and lag, then be stuck for a few mins, continue as normal, then start again 30 mins later, didn't start happening until after the Sept 4th Patch

[Kura]

ISP: Charter
Name: Kuranes'sae Dremr
Country: USA (Madison, WI)

Occurance: particularly in any city, fate, or dungeon. Game stutters and lags badly for a minute or two, game will proceed (sluggier and slower than previously) and will probably stutter and lag badly when rejoining populated areas or when FATE mobs spawn.

Was working perfectly before the update last week. Every phase of beta had nowhere near this kind of lag spike...it's very noticeable.
