On Northcliff Tower, half of its last 3 outages lasted at least 25 hours

This is not a forecast. It is how long past outages lasted. Each dot is one past outage, placed by its length: the last 3 outages on Northcliff Tower. A hollow dot with an arrow had no reported end: JW's reports stopped before it ended, or it was still going at JW's last report. Either way it lasted at least that long (2 of 3).

In words

2026 so far: JW reported it at “poor pressure to no water” or “critically low” on 3 days. JW published a report for it on 58 of the 272 days in the record; the other 214 days have no report, and we do not count them as normal. The median supply in the city had 4 such days.

2025: JW reported it at “poor pressure to no water” or “critically low” on 2 days. JW published a report for it on 63 of the 304 days in the record; the other 241 days have no report, and we do not count them as normal. The median supply in the city had 1 such day.

The last 3 outages JW reported on this supply lasted a median of at least 25 hours; the longest at least 2.5 days. 2 of them had no reported end (still open, or JW's reports stopped), so they count at the length so far. This is a record of the past, not a forecast.

JW's boards first named Northcliff Tower on 3 March 2025 and last on 29 September 2026: 179 statuses on 179 boards, over 121 days. 7 of those statuses announced a scheduled overnight closure, which we count apart, never as an outage.

Past outages

Each row is one outage: a stretch of time JW reported Northcliff Tower at “poor pressure to no water” or “critically low”, newest first. An outage has no reported end when JW's reports stopped before it ended, or when it was still going at JW's last report; its length is then a minimum.
