Looks like a BGP routing problem from where our local ISPs connect to the USA in Socal, to Tsikot.com's servers hosted by Amazon in Norcal.

VPN works because it lands on a different route. You can see the first big hop on the VPN traceroute landed somewhere in Texas, then followed a different path to the Tsikot servers.

IMO nothing wrong with PLDT or Globe. The problem happened entirely on the US side.
