An operator partner have been requested by UK operator EE to cease all lookup traffic towards their network with immediate effect. At this time HLR (legacy) and home_network lookups to UK EE subscribers will fail. Please note that hashed_imsi and get_country lookups to UK EE subscribers are not affected by this issue, nor are HLR (legacy) or home_network lookups to other UK networks or other countries. We are working with other operator partners to find a suitable replacement and will update this incident in due course.
monitoring Aug 16, 2019, 04:46 PM UTC

We have rerouted lookup traffic towards UK EE to an alternative operator partner and will continue to monitor traffic statistics.
