Power problems at Marine House led to the failure of some Eircom
equipment that connects us to the Symphony ATM network.
The ATM circuits UCD, TCD, TRBDI conenctivity lost. ITnet re-routed
over 2 m serial line. Non-Eircom ATM circuits (TEN-155, New York)
and DASSnet circuits are unaffected.
Eircom have found an SDH problem and they are working on it at that level.
16:10 Eircom engineer on site investigating NTU and configuration.
19:30 NTU couldn't be brought up; Eircom still trying to source a
working replacement. Keeping the office open should they find
one this evening.
23:00 Working replacement NTU with two cards sourced, software uploaded and re-installed at HEAnet.
23:59 UCD,TCD,TRBDI,ITnet reachable. Traffic flowing.
On Friday 24/12/99 from 07:30am to 10:00am Eircom will do an software upgrade on the ATM switch in HEAnet headquarters at Marine house.
The outage at most will be for 30 minutes over this time period.
However no site will lose connectivity for more then five minutes at a time.
