Hi everyone,
I've had Centurylink's 40/5 service for about 20 months now in the Westminster, CO area (old Qwest territory) and everything was great for the first 18 months--I could max out my line at 4.6MB/sec with the over-provisioning. But since December 2013, my connection speeds have gotten frustratingly bad--I rarely get above 3.5MB/sec with data transfers and, sometimes, Netflix and Amazon can't stream in HD quality. Most of the time, my throughput is 25mbit or less. This behavior is consistent--it's not a weekend or evening slowdown.
I've contacted Centurylink's TalkToUs email and a tech checked out my line stats along with similar data I provided and they say everything's peachy. They say my DSLAM port isn't overloaded. They sent a second modem (both are Actiontec Q1000) but the poor performance is the same with the replacement unit. I use my Actiontec in bridged mode with the PPPOE being handled with a downstream Pfsense router. The behavior is also the same when I bypass all the routing and plug straight into the modem with a laptop directly handling the PPPOE (to rule out my network).
I've attached a packet-by-packet throughput graph of an FTP transfer I just did from USC (their 1000mbit linux mirror) along with my modem stats and a traceroute to the same USC server.
Anyone have any ideas as to what on Earth is going on? Did Centurylink's peering take a dump in the last 2 months?
Regards,
John
