Performance to Cuba
•
Continuous measurements into Cuba
reveal diurnal patterns of latency spikes
•
Consistent with congested links – Internet
gets slower when more people are online

However, latency spikes occur only during
weekdays
•
Cuba is mostly online during work days,
little home Internet access
