Pretty big Zen outage
« on: July 25, 2016, 06:36:26 PM »

No web access, all websites unresponsive for the past 2-3 hours and ongoing in my case though I can still ping & get a response from everything I've tried.

Seems to affect circa 200 exchanges listed below, scattered around the UK.    :o

I wonder if it's just Zen, or are other ISPs affected?

Not directly, as exchange is not mine. But erratic speeds and pings since outage began.

"Our suppliers engineers are still investigating the cause of the outage."

Sounds like a BT Wholesale/Openreach issue to me. Probably also affects other SPs.

Yeah, this is not a direct Zen issue, failure of 3rd party supplier. Just like the BT/Plusnet issues of the past days. https://twitter.com/zeninternet/status/757593282994114560

And there it is, Zen say it is affecting multiple ISPs. BT Wholesale issue it seems. https://twitter.com/zeninternet/status/757636258084614145

It is in fact not affecting BT, that is a separate outage it appears. Apologies.

Still down, that's at least 4 hours now in my case. >:(

The list of exchanges seems curious, with no obvious connection (excuse the pun).   ???

I see The Register is already on the case...

http://www.theregister.co.uk/2016/07/25/zen_isp_network_out/

We obviously need to wait for the explanation but I'll certainly be expecting a very good excuse as to why it is, that whatever kit has gone pop, was not replicated for fault tolerance and redundancy. :(
