Subject: [ Speakeasy ] Notice: Network Outage in NYC - Recap


   

Dear Speakeasy Member,


We sincerely apologize for the network outages beginning

Wednesday afternoon and continuing into Thursday morning. 

Included for your reference is further information on the nature

of this outage and how it was resolved.


Wednesday afternoon, we received a complicated Distributed Denial

of Service (DDOS) attack and immediately began working with our

upstream providers to resolve it as soon as possible.  The cause


for the attack was not apparent, but subsided after multiple

filters were put into place.  After resolving this, it was

necessary to go ahead with our planned outage during the

Maintenance Window that night in order to complete our NYC POP

Upgrade.


Thursday morning, we experienced a simpler series of two large

DDOS attacks, one consisting of 600-800MB that we blocked by the

filtering implemented last night and the other consisting of

200-300MB attack on a specific customer's IP address, which we

immediately blocked.  This final attack has been identified as


the result of this specific customer's activities online and we

are gathering information to file a complaint with the FBI

against the attackers involved.


We are rigorously and actively investigating new methods and

technology options that will assist us in resolving these types

of attacks more quickly in the future. 


Again, we apologize for the inconvenience that these attacks may

have caused you and appreciate your patience while we worked to

resolve.
