Square Enix on Network Delay and Packet Loss Issues

Recommended Posts


Square Enix has addressed a concern that has been making the rounds in the community lately. There have been reports of network delays and packet loss for players which doesn't seem to be originating from the server side.

Most of the reports have come from Japan, but that doesn't mean there aren't reports from the other side of the world.

Naoki Yoshida explains what packet loss is and provided instructions on how to deduce lag as well as obtain traceroute information to be included in reports to Square Enix. As someone who is unfortunately not very tech-savvy, I appreciate the guidelines they gave us to help them investigate the issue!

Is packet loss an issue you happen to be struggling with too? If so, don't hesitate to send Square Enix a report!


Square Enix LogoSharing Information Regarding Network Delay and Packet Loss for FFXIV (Source)


This is Naoki Yoshida, Producer and Director of FINAL FANTASY XIV.

Since around the release of Patch 6.1, we have been receiving reports from players in Japan and other parts of the world stating that they have been experiencing network-related issues, such as a few seconds of network loss, or lag.

We are currently investigating the matter; however, we have not detected any issues on the development server. Based on the information that most of the recent reports are specifically coming from Japan, while others are playing without issue, the network-related issues may be due to the network routing. In the past month, some of the internet service providers (ISP) in Japan have been reporting issues due to high network concentration or trouble related to construction. That said, it may still be possible for us to contact the ISP and work together to see if we can resolve the issues.

The following covers the main causes of network issues, such as packet loss, and how to address them, as well as information we would like you to provide to us. Please submit your information through our support form.

* Please submit a report through the "Providing information on packet loss and lag" section located at the bottom of the Contact Us page.

What is Packet Loss?

Your gaming hardware and FFXIV server are connected via an internet connection and FFXIV works by sending and receiving data called packets on this network. A packet loss occurs when the packet data generated from your gaming hardware or the response packet data from the FFXIV server is lost on the internet path. A packet loss can cause your game screen to stop for a few seconds, or make it feel like your game is frequently lagging.

Additionally, these issues are more prevalent in online games where transferring data is required in real-time, and less noticeable for video feeds, such as those on YouTube and Twitch where the data is accumulated and streamed. In FFXIV, player inputs need to be processed in real-time, and therefore, the data cannot be streamed.

How to Investigate Packet Loss and Lag

If you feel you may be experiencing packet loss while playing FFXIV (such as the game screen stopping from time to time or large delays), please investigate and provide the following information:

  • (PC/Mac users) Please provide your traceroute results.
    * Instructions are listed below.
  • Please provide information about your ISP.
    Details such as the name of your ISP and the type of internet connection you use.
  • Where are you connecting from?
    Please provide the name of your country, state, and city.
  • What time do you experience the issue?
    Instead of broad statements like "constantly," please provide the approximate time frame and your time zone.
  • The frequency of the network issues.

For investigations into network routing issues, information regarding your ISP and location is much more valuable compared to your hardware specifications. We may be able to provide information to the carriers we have relationships with to investigate the matter based on the information we receive.

Please note that we won't be able to contact every ISP, but we'll do our best to ask the providers to investigate the matter. Even if we are unable to request an investigation from some of the ISPs from our end, the situation may be improved if players can provide this information to their ISP.

We would like to continue to provide information regarding network issues and methods for investigation. Understanding your network situation is crucial in order to play online games in a stable environment. The FFXIV Operations team would like to support users as much as we can, so we ask you to please continue to provide this information to us.

How to Obtain Your Traceroute Information

* Images and instructions below are from Windows 10.

1. Right click on the Start button


2. Click on "Windows PowerShell"


3. In Windows PowerShell window type "tracert [IP address of your data center]" and hit Enter.


IP addresses for each of the physical data centers are as follows:
Japan: (traceroute
North America: (traceroute
Europe: (traceroute
Oceania: (traceroute

4. Once the traceroute is complete, copy the traceroute results (the red section shown in the example below) and paste them into the form.



1. Open the Applications folder


2. Open the Utilities folder


3. Open the Terminal


4. Type "traceroute [IP address of your data center]" and hit Enter.


IP addresses for each of the physical data centers are as follows:
Japan: (traceroute
North America: (traceroute
Europe: (traceroute
Oceania: (traceroute

5. Once the traceroute is complete, copy the traceroute results (the red section shown in the example below) and paste them into the form.


By running a traceroute, you can track information such as the network pathway a packet has taken from your hardware to the FFXIV data center, the response speed from each route it passes through, and the frequency of packet loss that may occur in the pathway.

      In yesterday's Live Letter, new Endwalker relic weapons were revealed to be tied to the Hildibrand questline.
      Relic weapons have been a popular staple of the series since ARR, as it is not only stylish but is also considered BiS (best-in-slot) for its expansion. Therefore, relics are quite mandatory for players concerned with keeping their gear up to date for endgame content.
      Relic unlock requirements for every expansion up until now has been fairly run-of-the-mill. Finish the relevant MSQ, talk to a certain NPC, unlock a new zone (Stormblood and Shadowbringers), and farm Fates or dungeon roulettes for materials to upgrade your relic weapon. Often, this in itself is a tedious and time-consuming process, one that is meant to showcase how hard-earned relic weapons are. 

      Public opinion was polarizing at best when it was revealed that Endwalker relics are tied to Hildibrand. Some reacted with hilarity and took it in stride, some were supportive, and many reacted with profound irritation. Some broke meta ground. And some were simply genuinely puzzled. Such divisive reactions were to be expected, as the Hildibrand questline is notorious not only for having a very specific brand of humor, but also for being incredibly long. 
      Hildibrand follows the story of detective and gentleman extraordinaire Hildibrand Manderville with his trusty sidekick Nashu as they go through various misadventures alongside the Warrior of Light through the land of Eorzea. Each cutscene thrives on wacky mishaps animated with a fidelity that not even ARR MSQ cutscenes possessed. I admit, I was in awe at the quality of the cutscenes in the context of both animation and comedic value — I caught myself gasping out loud at the sheer absurdity of the things they came up with, as well as occasionally descending into side-splitting laughter. 

      Hilarity aside, the storyline spans 40 quests and 3 trials, with quests in ARR and Heavensward being the lengthiest. In total, this would mean players would have to go through an upwards of 10 hours of content to unlock the relic quest, not to mention the actual grind itself. This does not include the additional quests they are adding for Hildibrand in the upcoming patch. 
      This is by far going to be the longest relic journey yet. What do you think of the relic weapons being tied to Hildibrand? Are you excited to see what the Manderville weapons would look like? How far are you in the quest to complete Hildibrand, or are you a Gentleman Extraordinaire completionist?

      If you couldn't make it to Japan for the concert, now you can enjoy it at home! It will be less crowded, at least.

THE PRIMALS are most known for performing songs from FFXIV at Final Fantasy XIV Fan Festivals, headed up by the game's composer Masayoshi Soken.

      Square Enix isn't wasting any time building on the popularity of the new PvP mode, announcing the European Community Cup!
      Since it was announced, Crystalline Conflict was awaited with bated breath. FFXIV players were used to the Feast - a 4v4 arena-style combat which is no longer in the game - or they played Frontlines, a 24v24v24 battle that tends to get chaotic. Rival Wings, a third PvP mode, remains in the game but doesn't see very much play outside of special events (even though it's my favorite).
      But since it's been released, the new 5v5 Player-versus-Player mode in FFXIV has been highly praised. Some streamers and creators believed it would fail, and still might - however popularity for Crystalline Conflict shows no signs of slowing down.
      Frequent readers here might recognize one of the commentators for the tournament, as Brian Ricardo has collaborated with us on a number of projects in the past! Joining him will be Lythi, and the two will shoutcast the entire event. All matches will be broadcast on the official FFXIV Twitch channel.
      So for those of you on Chaos and Light, build a team and get to practicing! Registration is open as of yesterday, and brackets will be announced July 18th! The Crystalline Conflict Community Cup (say that five times fast) will be live on July 21st and July 22nd.

      Square Enix will be adjusting the wards available for private purchase in order to keep up with player demand.
      Announced last week, Square Enix released a lodestone post regarding revisions to housing wards. At current, Free Companies looking to purchase a house were given priority in Wards 1 to 18 in each of the five housing zones: Mist, Lavender Beds, The Goblet, Shirogane, and Empyreum. The remaining wards, 19 to 24, were reserved for players looking to purchase private, individual housing.
      As there has been more of a demand for the latter, Free Companies will now only have priority in Wards 1 to 9, while private buyers will have priority in the lottery system in Wards 10 to 24. Although this change was announced last week, the categories will not change until July 10th.
      What do you think about this change? Have you been able to get a house yet with the addition of an entirely new zone? Let us know below!
      Revisions to Housing Ward Classifications (Source)

      To accommodate housing demand, the classification of wards dedicated to free company/private plots will be revised.
      Scheduled Implementation
      These changes will take effect with the commencement of the entry period beginning Sunday, July 10, 2022 at 8:00 a.m. (PDT).
      Revised Housing Ward Classifications
      Housing classifications for each World will be revised as follows.
      Free Company Housing
      Previous   Revised Ward 1 to ward 18   Ward 1 to ward 9 Private Housing
      Previous   Revised Ward 19 to ward 24   Ward 10 to ward 24 * Housing areas for the four New Worlds added to the European data center will be classified differently. Further details will be announced at a later date.
      * Revisions made to ward classifications will not affect any previously purchased plots.
