Re: Disaster Recovery Process

2021-10-06 Thread Wolfgang Tremmel
And a layer 8 item from me:

- put a number (as in money) into the process up to that anything spend by 
anyone working on the recovery is covered.

Has to be a number because if you write "all cost are covered" it makes the 
recovery person 2nd-guess if the airplane ticket or spare part he just bought 
is really covered.

Additionally you should put an "approver" on the team who approves higher cost 
on very short notice.

Re: Famous operational issues

2021-02-19 Thread Wolfgang Tremmel
Do you remember the Cisco HDCI connectors? 
https://en.wikipedia.org/wiki/HDCI

I once shipped a Cisco 4500 plus some cables to a remote data center and asked 
the local guys to cable them for me.
With Cisco you could check the cable type and if they were properly attached. 
They were not.

I asked for a check and the local guy confirmed me three times that the cables 
were properly plugged. 
At the end I gave up, and took the 3 hour drive to the datacenter to check 
myself.

Problem was that, while the casing of the connector is asymmetrical, the pins 
inside are symmetrical.
And the local guy was quite strong.

Yes, he managed to plug in the cables 180° flipped, bending the case, but he 
got them in.
He was quite embarrassed when I fixed the cabling problem in 10 seconds.

That must have been 1995 or so

it does scale.
We do this for all our routeservers at all exchange points we operate.
In Frankfurt we have 745 peers on our routeservers.

(And: we are not a country but an exchange point operator :-)
