For example http://www.hotels.com/ were 32 and 40 milliseconds slower (from US and EU locations respectively) in week 46, compared to week 45. Website load speed was improved in week 46 by 103 and 136 milliseconds respectively, but in week 48 it slowed down again by 90 and 58 milliseconds respectively. Uptime of http://www.hotels.com/ went down from 100% to 99.5% in week 47 and to 99.2% in week 48. About 11 hours off!
The diagnostics of the problem would help to find the reason and correct the situation.
On 28 November the monitoring report showed for example that the site was down from USA and Germany several times during the day. It was also quite slower Austria 5.6 - 6.5 seconds load time. See the chart below:
Mon.itor.Us also provides free visitor statistics counter. If calculating hourly traffic how much visitors has the site has been loosing during 11 hours downtime.
