Dear Customers,

We have been advised of the following planned maintenance work being carried out at the TelecityGroup Memaco House:

Description:

TelecityGroup will be carrying out a deep clean of customer suites and data floor areas at Memaco House from the 11th – 22th June 2012.

Please be advised that our specialist cleaning contractors will need to enter your dedicated area to carry out the deep clean. Any spare equipment or items on the floor will need to be cleared or moved to enable the cleaning works to be completed. Please make arrangements to clear any items on the floor within your area prior to commencement of the deep clean. If any items are found on the floor when our cleaning contractors enter your area, TelecityGroup’s engineers will move the items to an alternate location and place the items back once the cleaning is complete.

The cleaning contractors will ensure that suites doors are closed and as an additional security measure, TelecityGroup has arranging for dedicated security personnel to be in attendance whilst the cleaning contractors are working in your area to maintain our high security levels.

We do not anticipate any impact to your service whilst these works are ongoing. There may be short periods when some floor tiles in your area are raised during the cleaning works, however this will have minimal impact to the cooling in your area and the tiles can be promptly reinstated back into position if you need to access your dedicated area.

Contact:

If you have any major works planned during the deep clean window, please raise a support ticket on the support site, https://support.c4l.co.uk or give the technical team a call on 01202 299799 ext. 3. and we will reschedule the planned deep clean date of your area if it coincides with your scheduled works.
