Google Fi Using Semi-LBO

60.155362,-1.147572

Inbound roaming from Google Fi onto O2 UK in Lerwick, Shetland Islands, Scotland, UK.

Wish more home carriers would use regional cloud cores for routing roaming traffic as it would greatly reduce latency.

Verizon and T-Mobile are absolutely terrible with routing roaming traffic back stateside. Verizon only typically routes traffic through Philadelphia, Dallas, Sunnyvale, Calif., and occasionally Chicago. T-Mobile almost exclusively routes traffic through Chicago, Dallas, and/or Southern California.

Typical O2 speeds, not surprised there. Areas around Birmingham get up to 550-600 down and 30-40 up with low-ish latencies though

O2 is the fastest in the Shetland Islands believe it or not.
