Twitter is one of the hottest social networks online but it continues to struggle with their uptime problem.
Akamai has reported that the micro-blogging service experienced more downtime than any other social networking site last year.
The report said that Twitter was down for around 84 hours last year.
LinkedIn was on the second spot with around 46 hours of downtime.
Facebook did very well to land on the 11th spot with just 7.2 hours of downtime.
