Our Internet connectivity suppliers in our main Sydney Data Centre POP have been doing updates (mostly software based) to their Sydney based routers and networks, and though we pay for a supposedly redundant service there with multiple physically separate fibre links, we saw a short issue across both links at the same time late one night last week, at the time window when the supplier had advised us of the works, but said we’d have no downtime.
They have more network reconfiguration work further in their core networks in Australia tonight and again they advise no downtime, but I’m not convinced.
There could be short Internet connectivity breaks to some Australian/domestic networks this evening as they update their main core routers software configuration, from 11pm through to 5am, with any outage expected to be short (minutes), on the night of Tuesday November 7th 2023 and the morning of Wednesday November 8th.
As you may’ve heard, this update of our upstream was coordinated in time with the works by Optus on their network’s BGP settings.
We’re not using the settings that were updated in the domestic BGP network that could bring our network “closer” to Optus and I’m glad for that after what happened to Optus’ network last week.
So my suspicion of trouble in this upstream network update was right & thus this post was worth putting out on this upstream network’s updates.
