Re:Amazon EC2 and RDS in US-EAST zone down on Friday June 29, 2012 @12:04PM (#4177312)
That's really interesting if it's true. I had never heard this before. Thanks for the tip.

Both my MySQL master (I'm not using RDS) and Redis Master servers are affected and are located in zone us-east-1a.

Cpu0 : 0.3%us, 0.0%sy, 0.0%ni, 0.0%id, 99.7%wa, 0.0%hi, 0.0%si, 0.0%st <-- EBS subsystem is completely unreachable. I/O wait times are tanked across the board for me (I'm in US-EAST-1).

Are you sure? I have a graph of one of my Resque boxes taking 30Gbit/s of inbound traffic. Looks like a DDoS attack to me.
Re:EC2 to VPC: A transition worth doing. on Thursday November 03, 2011 @03:10PM (#3193227)
The showstopper for us when it came down to whether we will use VPC or not ended up being a no due to lack of support on elastic load balancing:

I will certainly revisit this topic when ELB is inevitably available for VPC based customers.

Re:Sharding and IDs at Instagram on Friday September 30, 2011 @06:25PM (#3058773)
Not really. Like MongoDB, the first four bytes of an ObjectId are a timestamp. That the timestamp is synced with other instances isn't paramount because the actual value of the timestamp does not matter. What does matter is that the timestamp is new and increasing every second. This is to retain sorting capabilities. With the 13 bits that represent the logical shard ID from this article, Instagram will guarantee uniqueness of an ID within the granularity of a second.
