Connectivity to and from the Servology network was degraded from approximately 11:20 to 13:00 on Friday 22 July 2022, due to faulty hardware in our main transit provider’s network. Once I had determined that the problem was caused by a fault outside the Servology network, I resolved the problem by shutting down our connection to our main transit provider and failing over to our backup transit provider. Our main transit provider declared a Major Incident and worked to stabilise their network. I reestablished our connection to them the following day in off-peak hours once it became clear that their network was once again stable. This fault affected access to several (but not all) web sites and other services hosted at Servology.
