Thanks for the ping, this seems to be a single rack problem - https://netbox.wikimedia.org/dcim/racks/77/ (rack 603)

19:21  <elukey> it seems a PS redundancy failure for one rack, but I didn't get the asw1-eqsin down alert                                                          
19:22  <elukey> PROBLEM - Host asw1-eqsin is DOWN: PING CRITICAL - Packet loss = 100%                                                                              
19:22  <XioNoX>  UTC:ISATURDAY, 03 JUL 14:00 - SATURDAY, 03 JUL 22:00 for the Equinix maintenance                                                                  
19:22  <elukey> ah right before the PS failure, lovely timing
19:22  <elukey> okok
19:22  <XioNoX> elukey: probably because we lost asw1 mgmt before it could alert
19:22  <XioNoX> checking the CR
19:23  <XioNoX> @cr3-eqsin> show system alarms
19:23  <XioNoX> 2021-07-03 14:19:26 UTC  Major  PEM 1 Not Powered
19:23  <elukey> I asked to Traffic to check later on, Valentin should be home later and will verify if we have to do anything or not for the PS failure (in theory 
                no but not sure)
19:23  <elukey> can you translate? :D
19:24  <XioNoX> elukey: unless Equinix unplugs the wrong power feed we should be good                                                                              
19:24  <XioNoX> elukey: see "SERVICE IMPACTING MAINTENANCE Scheduled Customer Outage in 1 hour: Shutdown Maintenance of PDU, ACB and LV Switchboard at L6 A2 at SG3
                [5-206136314890]"
19:24  <XioNoX> basically equinix is doing power maintenance on the power feeds
19:25  <elukey> ah okok now I get it, I didn't think about checking these things in the mailing list                                                               
19:25  <elukey> going to update https://phabricator.wikimedia.org/T286113
19:25  <XioNoX> after they're done we will need to check that everything came back up too

So nothing on fire, In Equinix they are performing some maintenance, we'll need to check later on if everything comes back fine.

Info about a similar use case (credits to Arzhel): https://phabricator.wikimedia.org/T206861#4664474

Things to decide:

  1. Do we need to depool eqsin?
  2. Do we need to contact Equinix for any follow up?

It seems that also rack 604 is affected, so both eqsin racks. Created a code change to depool eqsin as precautionary measure, but I'd need the Traffic team's approval first.

[operations/dns@master] Depool eqsin

https://gerrit.wikimedia.org/r/703031

elukey added a comment.Jul 3 2021, 5:54 PM

Me and Arzhel decided to depool eqsin, the PS redundancy failure's maintenance window seems to be:

UTC:	SATURDAY, 03 JUL 14:00 - SATURDAY, 03 JUL 22:00

Next steps:

  • check varnish traffic on other DCs, we should be ok but better to double check
  • wait for the PS redundancy issue to be fixed, then check that al PSes are up etc..
  • read https://phabricator.wikimedia.org/T206861#4664474 to avoid the same mistake again :D
  • repool eqsin

The problem seems to be fixed, and just to be sure:

Only nit - cp5006's mgmt is still not reachable, we should follow up.
