There's one pair of twisted copper coming to a punchdown block just outside, and neither the owner of the copper or their competitors seem to be motivated to provide a DSL package I consider really acceptable.

Connectivity issue between Verizon and Amazon EC2
I'm short some important details on this one, but hopefully can fill in more shortly. We're seeing poor performance (very slow download speeds -- 100KB/sec) to certain EC2 instances via our Verizon hosted circuits. The issue is reproducible on both our production Gigabit circuit as well as a consumer grade Verizion FIOS line. Speeds are normal (10MB/sec plus) via non-Verizon circuits we've tested. Source IP's are in the 198.102.62.0/24 range and destination on the EC2 side is 54.197.239.228. I'm not sure in which availability zone the latter IP sits, but hope to find out shortly.

The issue is reproducible on both our production Gigabit circuit as well as a consumer grade Verizion FIOS line. Speeds are normal (10MB/sec plus) via non-Verizon circuits we've tested. Source IP's are in the 198.102.62.0/24 range and destination on the EC2 side is 54.197.239.228. I'm not sure in which availability zone the latter IP sits, but hope to find out shortly.

The 140.222.225.135 shows up in the traceroutes via our Verizon Business FIOS line as well. Will be opening a ticket with both Verizon and AWS to assist, but hoping someone out there can take a look or chime in. Feel free to reply off list. Thanks, Ray
