[lacnog] Prefix Hijacking

[Carlos M. Martinez]

Dear Lucas,

You need to open a ticket with your transit provider then. The fact that 
the announcement is still seen after you removed it is either due to a 
“stuck” route (unlikely, but possible) or due to a common 
“trick” used by some lazy transit providers who anchor their 
customer routes to local null0 statics or similar.

In either case, it’s your transit provider who needs to fix this.
