Dear RIS engineer/users, Greetings! I've been seeing inconsistent and slow download speed when trying to access RIPE RIS MRT files from the US. I'd like to share what I observed and I hope this could be helpful in resolving the underlying problem. In early January, I noticed a consistent sub 500KBps download speed, observed from multiple locations myself (from boxes at ATT, Equinix Metal, and via Cloudflare WARP). I also posted a quick twitter survey and received multiple responses saying the same https://twitter.com/heymingwei/status/1742959348396220557. The situation seems to be resolved a few days later, going back to 20MBps speed at home for me. Today, I again see consistent <1MBps speed from the US west coast at home with 1Gbps symmetric link (AS7018 ATT). [image: image.png] Here is the traceroute from my location (no VPN, 1Gig ATT fiber) to data.ris.ripe.net: ➜ /tmp traceroute -a -q 1 data.ris.ripe.net > traceroute to ftp.ripe.net (193.0.11.24), 64 hops max, 52 byte packets > 1 [AS0] unifi (10.0.0.1) 2.858 ms > 2 [AS0] 192.168.1.254 (192.168.1.254) 0.899 ms > 3 [AS0] 108-238-20-1.lightspeed.sndgca.sbcglobal.net (108.238.20.1) > 4.446 ms > 4 [AS7132] 71.157.6.120 (71.157.6.120) 4.558 ms > 5 [AS7018] 12.123.215.174 (12.123.215.174) 16.459 ms > 6 [AS7018] la2ca22crs.ip.att.net (12.122.2.69) 14.652 ms > 7 [AS7018] ggr2.la2ca.ip.att.net (12.122.129.105) 10.493 ms > 8 [AS0] ae7.cr4-lax2.ip4.gtt.net (199.229.231.29) 9.350 ms > 9 [AS3257] ae1.cr3-ams2.ip4.gtt.net (89.149.128.117) 170.055 ms > 10 * > 11 * > 12 * > 13 * Please let me know if there is any other info that I can provide that may help.
