During this engineering window LINX (a major UK connection point used by numerous ISPs) are upgrading their routers at Telehouse North. This may lead to periods of routing issues overnight as various ISPs including us are moved between the old and the new hardware. This might also mean that some sites are unavailable or slow for short periods of time at various times during this period. If you are still seeing problems after this time please log a support call or ticket in the normal manner.
