Some weeks ago, the day Skype reached 7 million concurrent users online, we noticed a strange and brutal dip in the number of users online, and this around or just before peak time.Today a similar phenomenon occurred, also around peak time, being around 14h GMT:
This makes me think that our assumption that this was a Skype induced phenomenon (like resetting Skype owned Super Nodes or count servers) was indeed correct.
This graph was “captured” from the Japanese website nyanyan.to
The other dip some hours earlier on the chart is a “normal behaviour” dip!
I don’t think it is a good idea to do this around peak-time, unless it doesn’t affect the working of the Skype cloud!
