Notice posted at PR host regarding major failure:
Dear [ISP] Customer:
This is to inform you of the events of Sunday, December 3, 2006 which resulted in a [ISP] network outage.
At approximately 10am on Sunday, December 3, a major network event occurred whereby all circuits from Puerto Rico to Miami reported failures. After extensive research to troubleshoot this error, a major undersea fiber cut was found. The fiber cut appears to be in the waters off the coast of Punta Cana [Dominican Republic].
[ISP's] main redundancy, which consists of routes on alternative fiber paths, had been scheduled by our partners for maintenance repairs. Therefore, our main redundancy circuits had been temporarily moved to the same cable as the primary circuits for this maintenance window.
[ISP] maintains agreements with local providers to exchange local internet traffic on-island and to route all traffic via these providers in the event of a major network event. Unfortunately, this fiber cut has affected almost all providers in Puerto Rico. [ISP] was able to restore service by 10pm on December 3, 2006. However, bandwidth is significantly limited for all providers on the island, as we are all sharing resources.
The current prognosis is as follows:
1. We expect that bandwidth will increase as the day passes; we are hopeful that we will be able to add more capacity via new alternative routes. 2. The maintenance and repairs of our main redundant circuit in the Gulf of Mexico has been accelerated by our partners and should be completed sometime by early tomorrow morning (Tuesday, December 5). Full service should be restored by mid-morning on Tuesday, December 5. 3. In January 2007, a new cable will be put into service via the US Virgin Islands. This cable will offer additional redundancies and alternatives for the future.
The cause of this failure has not been determined at this time - whether it was negligence by a partner, an Act of God, or other possible cause. We will keep you posted on this.
I read on a local paper yesterday that the Puerto Rico - Miami cable carries some traffic from South America so that might have been it.
