From eircom website:
(Tuesday, 22nd July 2008) eircom is currently implementing a series of DSL broadband speed upgrades which will significantly increase Internet speeds available to a large portion of eircom's retail and wholesale customers.
The upgrade programme consists of two stages:
1. The installation of ADSL2+ equipment in 117 of the largest exchanges in Ireland.
2. An automated software upgrade for the majority of eircom retail and wholesale customers currently on 2Mb or 3Mb broadband.
Stage 1 - ADSL2+ Upgrade
The installation of ADSL2+ equipment to our largest telephone exchanges allows eircom to offer speeds of up to 12Mb on its network. This process has been completed in more than 100 exchanges to date. Existing broadband customers, previously on 4Mb or 6Mb broadband, that have a line which qualifies for the faster speeds and who are connected to one of the following exchanges are in the process of being upgraded to 10Mb and 12Mb respectively.
