Tracking down HTTP push notifications

We were recently contacted by one of our customers to investigate some popups that were appearing on one of their users' workstations.

The user, who was thankfully a member of staff, received a popup notification asking "Do you like big girls?" and featuring some fairly risqué pictures.  The customer was obviously concerned that this had not been picked up by their filtering and so asked us to investigate why this had happened.

Oracle Dyn outage

A number of large internet services use Oracle's Dyn service to host their domain's DNS.  This service has had an outage overnight (27 May 2022).  This problem was caused by a DNS misconfiguration and, although the underlying problem has now been resolved, it will take some time for the broken DNS records to be cleared from DNS caches around the world.

Bundled Filtering and Connectivity

Evolving Networks Logo

The Birmingham Grid for Learning, Rotherham Schools Connect, Worcestershire County Council and Essex County Council have all announced that they will no longer be providing internet connectivity and filtering to schools after the end of March 2020.  These announcements prompted us to consider how we can best support those schools who are now looking for a replacement service.
