In the very recent past there was a certain Tier 1 operator who decided to move a core router between X & Y within the same datacentre. As you might imagine, this impacted a good few hundred fibres. Physical move happened without issue, router powered up fine, but a large subset of fibres refused to come up. Cue escalation, lots of testing, lots of talking to vendors etc. Eventually 72 hours later the problem was solved. Cause ? SFP signals too high at new location, attenuators fitted, everything came up.
