Actually you are getting what you paid for. Broadband Service Level Agreement is best-effort, there is no clause gurantee on network latency or packet loss.

Well, it does load but just slower.

Between you and the european webserver, that are many components in between, and not all the time is the service provider fault.

The submarine cable is damaged and everyone is forced to fallback to existing capacity hence congestion happen.
There are huge chunk of traffic to be reroute, and to obtain additional capacity will not come at zero cost.

This is just like, you pay roadtax every year. During the festival time, you complain the road is jam and this is not what you pay for.
You expect the government to build a new highway from KL to your kampung in one or two days ?
