Kinda laughable, but this is the thread that SE support linked me as a way to say: 'We cannot help you further. Check this link.' And yes I'm being literal.

So yeah, I'm new (in the forums), and I'm here just because of this lag thing problem. Nice to meet you everyone.

Info:

Country: Chile
ISP: VTR Globalcom S.A
Traceroute explained: First 5 local servers avg. 20ms. Rest of the international servers (Level3 and FF XIV IPs) avg. 250ms. All of them located in the US and Canada.
My rig: Core i7 3770 3.4ghz, NVIDIA Geforce GTX 570 2gb, 8gb RAM, 1TB HDD, Windows 7 premium. Not getting into details because this will suffice for those talking about 'graphics lag'.
Network hardware context: ISP Cable modem Motorola Surfboard SB5101 connected to router TP-LINK TL-WR740N. Router has a network cable connected to my rig.

Situation: I've been playing this game for about 1 year. 3 weeks or so ago and never had any issues about lag. We moved to another house (the one next to where I lived before lol). We kept the same service, but obviously they re-wired everything in this new house, so I'm guessing they changed the IP of my modem which I kept too (my ISP has static IP which changes every 2 months or so). This is where the problems started, specifically, the 'everyone's problem' 5 or so seconds of lag spike, which is constant. At least for me, this situation happens from 12pm day time (gmt -3) to 12pm night time (gmt -3). Peak goes from 5pm day time to 10pm night time. This is when games is practically unplayable and yes I'm not being a whiner. It tecnically is unplayable.

Since I play lots of instances, specially coils, this situation is particular, because like everyone else states, the lag is notoriously higher and constant in these situations, and at least for me, it does not discriminate time. It can happen in AM or PM time, even if when I'm outside instances, the lag is present at the times previously stated. The odds are fewer in AM time, but they happen too.

So, started to wonder and investigate about all this problem, and did a tracert, so I could check the path my IP is taking to reach the game and also check the ping: Extremely low pings in first 5 IPs which I scanned, and they were locals. Then it jumps to 130 in a CDN located in US. After this we reach our beloved friend Level3, where my ping reaches 260-300ms. I've read about this and short story, for mmorpg, it is bearable, at least to not 'feel' a 5 second lag spike, and constant. Investigated further, and realized that Level3 is congested, meaning that lots of IPs are passing through this CDN, causing - something we call here - like a 'bottleneck'.

Finally, I began to gather all the pieces:

- ISPs (at least in my puny little country) doest not have control nor contact over external CDNs / ISPs to command them to change the route of an specific IP. They do have control over local servers.
- Level3 is congested
- Unbearable lag specially in afternoon - night.
- .... what the hell is SE doing about this? Can they contact these US / Canadian ISPs and CDNs about this issue?

Idea:

Since US ISPs can also have control over where are their IPs routing, they choose most of em to pass through Level3 (because it's local you know, duh), and since in the afternoon people leave work, they are tired and watch lots of Netflix and such, in this case Level3 collapses. ISPs point that some CDNs do not have the infrastructure, and CDNs points that ISPs are organized to pass most of their IPs through their servers. Yay. Ah yes, and for me since I have similar hour time as US, I get lag because it fits in the same time US ISPs clients are using internet the most. Oh..uh, where is SE in all of this?



What I've tried (1 by 1, simultaneously, rebooting, etc.):

- Port Forwarding.
- Google DNS.
- 3rd party programs to check best DNSs in the area.
- Leatrix latency fix.
- 3rd party VPNs like Battleping and WTFast.
- Played directly with modem, avoiding router.

None of the above worked, and believe when I say I tried like 10 times each of these.

So. Read some stuff in this forum, also in external forums and it seems to be some people that knows a lot about all of this. Hopefully they can answer some of my questions in this post, above all, regarding the role of SE and their servers in all of this.


P.S - A little warning about my English doesn't hurt.
