Nanase的随记
近期可以观察到 Kirino FRA CN2，已不存在去程绕沪问题，延迟有明显改善。 关联产品包括 Saltyfish / AKKO 欧洲CN2产品。 附图为多地到 Saltyfish.FRA.Pro 去程路由测试。 #咸鱼云

个人感觉最大的提升是接入RETN(AS9002)，作为参考：
to BER 141ms （via Russia）
to LON 157ms (visa Russia)
to AMS 152ms (visa Russia)
to HKG 42ms
to SIN 72ms
to SEA 92ms

还有一些升级商家没注明，但是确实会有：
接入BBTEC（纯国际），提升日本本地资源互联体验；
到HKG、LAX的低延迟L2，也在进展中。
（由于商家未注明以上内容，应当视为NO Guaranteed / Best Effort）
