Squirrel chew. Apparently, that's one reason 27C is still dark.
A Sonic crew set up shop this morning on California, N. of Bancroft, splicing cables. I stopped to ask what they were up to, and one of them told me that a squirrel had chewed on the fiber. He said squirrels were their biggest enemies. I have fruit trees in my back yard, so I sympathize.
They should have it finished today and tested probably Monday. After that, things still need to be connected up at the CO, but he guessed it should go live sometime next week or the week after.
The tech I spoke to mentioned how much nicer it was working for Sonic, where customers were always happy to see him, than for his previous employer, an unnamed telecom utility (starting with an A), where customers were annoyed even before he arrived.
