Name of your Internet Service Provider (ISP): Comcast
Ticket or reference number from your ISP: Didn't contact.
State/Country: WA/US
Date/Time: 6:30PM PST - ~9:00PM PST
Frequency: The issue occurred randomly, with varying amounts of lag estimated between 1 - 5 seconds.
Content: I was just outside of Moghome and just outside of Falcon's Nest where I experienced it the worst. Long periods where I would be casting spells with no effect or MP usage shown, then all the missed actions would play in "fast forward". Standard lag. It seemed to be less severe when I was at my FC house in The Goblet, but there was still noticeable lag interacting with NPCs and the chocobo stables. The issue tapered off as the night wore on.
Which in-game World were you playing on when the issue occurred? Malboro
Traceroute records (optional): I don't have any, though I did switch to using Mudfish as a test to see if I could route around any trouble spots, but even jumping to various nodes (and with tracert showing that I was getting a completely different route once I left my ISPs network) didn't seem to have much effect. This may not have been the Level3 issue Comcast users have experienced in the past, as I'm fairly certain at least one of the nodes I used wasn't routing through Level3 (unless the datacenter the servers are hosted in peers with Level3 and there's no way around it, of course).
