Telkom said that planned maintenance to add new IP addresses to the network was behind the country wide ADSL outage which occurred on Friday, 7 June 2013.<\/p>\n
Telkom explained that on Friday at 15h30 its staff performed scheduled planned maintenance work to add new IP addresses to the ADSL network.<\/p>\n
\u201cThe type of planned maintenance undertaken was classified as non-invasive, low risk and a very mature process routinely used to add new IP addresses to the network,\u201d said Telkom.<\/p>\n
\u201cUnfortunately a problem occurred immediately after commencing the planned maintenance and this resulted in all live ADSL sessions being \u2018reset\u2019; commencing approximately 15h49.\u201d<\/p>\n
Telkom said that a standard session reset takes on average around 2 minutes, however, the high number of simultaneous reset attempts due to the problem put a significant load on authentication servers.<\/p>\n
This high authentication server load caused the resets to take longer than normal and were experienced by customers as downtime.<\/p>\n
\u201cThe focus, since the problem occurred, was on getting services working and stable as soon as possible,\u201d said Telkom.<\/p>\n
\u201cThis was largely achieved with most services being back up and stable since approximately 17h30 on Friday afternoon. Telkom has also confirmed this with some of the major ISPs\u201d.<\/p>\n
Telkom said it has now commenced an in-depth investigation into the scripts, processes and underlying network control elements to establish the root cause in order to prevent this from happening in the future.<\/p>\n
Telkom apologised to ADSL customers that have experienced an interruption to their ADSL services.<\/p>\n
