K'Abhisak krub,
Acknowledged your comment krub. Let us verify this concern and will update you shortly. So far, I just checked link between TIG-NIPA (20G) at Bangkok and TIG-Bangrak toTIG Muangthong thani/True Tower (80G) and found that there is no congestion with about 50% of utilization (during peak hour/weekend). Anyway, I will ask team to further verify and will let you know for any update.
Since I am abroad for business trip this week (until this Fri, 23 Oct), my response may be slow sometimes krub. Sorry for any inconvenience that may occur krub.
