This was an unplanned event, which may have impacted your service asdescribed below.\r\n\r\nStart: 2011-03-11 05:46 UTC\r\nEnd: Ongoing\r\n\r\nAffected Devices:\r\nr00.londen03.uk.bb.gin.ntt.net\r\n\r\nAffected Services:\r\nGIN-EU-SID1009896 (83.231.146.173)\r\n\r\nService Impact:\r\nAt 5:46:24 UTC according to US Geological Survey, a magnitude 8.9 earthquake struck off the east coast of Honshu, Japan, followed by a series of\r\naftershocks measuring greater than magnitude 6. Given the scale of the earthquake, and the continuing seismic activity, full impact of this event is not yet known.\r\n\r\nThis disaster has had impact on some Trans-Pacific cable system as well as some domestic fibre infrastructure in Japan.\u00a0 There is a high probability that traffic traversing Trans-Pacific will be adversely impacted during peak times. There is also likelihood that connectivity to various destinations in Japan may be adversely impacted as well.\r\n\r\nAs this is a developing situation, at this point there is no estimated time for resolution. We will be issuing updates as we obtain new information and the\r\nsituation clarifies itself.\r\n\r\nOutage Reason: International Unplanned Outage - Multiple Transpacific Circuits\r\n\r\nFor more information, please contact the NTT Communications Global IP Network Operations Center and reference problem report VNOC-1-951232041.\r\n\r\nThank you for your understanding.\r\n\r\nRegards,\r\nNTT Communications Global IP Network (AS2914)\r\nNetwork Operations Center\r\nEmail: noc@ntt.net\r\nTelephone (USA): 1-877-NTT-NOC5 (1-877-688-6625)\r\nTelephone (Outside USA): +1 214-672-7228","protected":false},"excerpt":{"rendered":"<p>    Hi All,Message below from TENET regarding international internet traffic.&nbsp; This may result in degredation to GridHPC resources.Please see below for a notice from our Internet Transit provider.It is very difficult to ascertain just how great &#8230;<\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":[],"categories":[18],"tags":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v21.4 -
