[Level 3 hat on]
I did respond privately but for other interested parties:
The problem in the trace below is in SJO. Poor load sharing congested
an uplink to a core router. Moved some traffic off congested link to
gain some room. Times should have improved after that. After that there
was a WAN link that was caught in that fiber cut yesterday that extended
the issue for traffic heading out of SJO.
thanks
