Meanwhile Eclipse Internet crashed back from Octobers impressive download rate of 3.899Mbps to hit a lowly 2.784Mbps this month. Its upload rate was also reduced slightly from 0.426Mbps to 0.393Mbps over the same period. We do not know the reason for this sudden spike and then subsequent fall.

UPDATE

Corrected Orange's upload figure due to an error in the source data.
